-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+
+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.
+
+```js
+assert.lengthOf(code.match(/console\.log\(\s*cities\s*\)/g), 2);

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```

+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+If the index is out of range, JavaScript will return `undefined`. Meaning that if you try to access `fruits[3]` in the above example, it will return `undefined`.

+
+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']

+
+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+Now that you have a basic understanding about arrays, let's talk about loops. Loops are used to execute a block of code multiple times. One of those loops is the `while` loop. The `while` loop executes a block of code as long as the condition is true. The syntax of the `while` loop is as follows:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:

+  console.log(i);
+}
+```
+

+
+```javascript
+const arr = [1, 2, 3, 4, 5];

+
+Now that you know about the most common ways to iterate over values and arrays, there are a few more ways to iterate over arrays. Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

 A configuration of type $(a,b,c)$ is a graph thus built of $a$ units A and $b$ units B, where the graph's vertices are coloured using up to $c$ colours, so that no two adjacent vertices have the same colour. The compound graph above is an example of a configuration of type $(2,2,6)$, in fact of type $(2,2,c)$ for all $c ≥ 4$

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
 
-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books.

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+# --description--
+
+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.
+
+```js
+assert.lengthOf(code.match(/console\.log\(\s*cities\s*\)/g), 2);
+```

-To format the date into `yyyy-mm-dd`, you will need to use the <dfn>split</dfn>, <dfn>reverse</dfn>, and <dfn>join</dfn> methods. But first, you will need to go through a few practice examples so you can better understand how to use them in the context of this project.
+要將日期格式化爲 `yyyy-mm-dd`，你需要使用 <dfn>split</dfn>、<dfn>reverse</dfn> 和 <dfn>join</dfn> 方法。 但首先，你需要通過一些練習示例，以便更好地瞭解如何在這個項目的上下文中使用它們。
 
-The `split()` method is used to divide a string into substrings based on a specified separator. It then returns these substrings as elements of an array.
+`split()` 方法用於根據指定的分隔符將字符串分割成子字符串。 然後返回這些子字符串作爲數組的元素。
 
-Here is an example of taking the words `"Hello World"` and returning an array of one element:
+這裏有一個將詞語 `"Hello World"` 轉換爲一個包含一個元素的數組的例子：
 
 ```js
 const greeting = "Hello World";
 greeting.split(); // ["Hello World"]
 ```
 
-Create a new `const` variable called `exampleSentence` and assign it the result of `"selur pmaCedoCeerf".split()`.
+創建一個新的 `const` 變量，命名爲 `exampleSentence`，並將其賦值爲 `"selur pmaCedoCeerf".split()` 的結果。
 
-Then add a console statement to log the value of `exampleSentence`. Open up the console to see the result.
+然後添加一個控制檯語句來記錄 `exampleSentence` 的值。 打開控制檯查看結果。
 
 # --hints--
 
-You should have a `const` variable called `exampleSentence`.
+你應該有一個名爲 `exampleSentence` 的 `const` 變量。
 
 ```js
 assert.match(code, /const\s+exampleSentence\s*=/);
 ```
 
-You should assign `"selur pmaCedoCeerf".split()` to your `exampleSentence` variable.
+你應該將 `"selur pmaCedoCeerf".split()` 分配給你的 `exampleSentence` 變量。
 
 ```js
 assert.deepEqual(exampleSentence, "selur pmaCedoCeerf".split());
 ```
 
-You should have a `console.log` statement that logs the value of `exampleSentence`.
+你應該有一個 `console.log` 語句來記錄 `exampleSentence` 的值。
 
 ```js
 assert.match(code, /console\.log\(\s*exampleSentence\s*\)/);
 ```

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```
+

+
+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+If the index is out of range, JavaScript will return `undefined`. Meaning that if you try to access `fruits[3]` in the above example, it will return `undefined`.
+

+
+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']

+
+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+Now that you have a basic understanding about arrays, let's talk about loops. Loops are used to execute a block of code multiple times. One of those loops is the `while` loop. The `while` loop executes a block of code as long as the condition is true. The syntax of the `while` loop is as follows:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+To iterate over an array using a `for` loop, you can use the array's length property. For example, the following code snippet prints the elements of an array:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];

+Now that you know about the most common ways to iterate over values and arrays, there are a few more ways to iterate over arrays. Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

 A configuration of type $(a,b,c)$ is a graph thus built of $a$ units A and $b$ units B, where the graph's vertices are coloured using up to $c$ colours, so that no two adjacent vertices have the same colour. The compound graph above is an example of a configuration of type $(2,2,6)$, in fact of type $(2,2,c)$ for all $c ≥ 4$

-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

 # --description--
 
 The `equals symbol` (`=`) is commonly used for assignment. It's used to assign a value to a variable. The variable name is written on the left of the equals symbol, and the value you want to store in the variable is on the right.
 
-For example, `name = "Sophia";` assigns the string `"Sophia"` to the variable `name`.
+For example, `name = "Sophie";` assigns the string `"Sophie"` to the variable `name`.
 
 To `assign a value` in programming means to give a specific value to a variable. The `equals symbol` (`=`) is commonly used for this purpose. When you assign a value to a variable, you are telling the program to remember that value for use later.

 JavaScript 有七种原始数据类型，`String`（字符串类型）就是其中之一。 在 JavaScript 中，<dfn>字符串</dfn>代表的是一串字符内容，被包裹在单引号 （`'`）或者双引号（`"`）之中。
 
-请注意，字符串是<dfn>不可变的</dfn>，这意味着它们被创建后就不能再被更改了。
+Note that strings are <dfn>immutable</dfn>, which means once they are created, they cannot be changed. The variable can still be reassigned another value.

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+

-In the previous project, you learned how to work with the `join` method. This method takes an array of elements and joins them into a string. Similar to the `split` method, the `join` method also takes an optional separator. If you don't provide a separator, the default separator is a comma.
+在之前的项目中，你学会了如何使用 `join` 方法。 这个方法接收一个元素数组，并将它们连接成一个字符串。 与 `split` 方法类似，`join` 方法也可以接受一个可选的分隔符。 如果你不提供分隔符，默认的分隔符是逗号。
 
-Here is an example of using the `join` method:
+下面是使用 `join` 方法的示例：
 
 ```js
 // returns "1-2-3-4-5"

 ```
 
-Chain the `join` method to your `reverse` method. Pass in an empty string as the separator.
+将 `join` 方法链接到你的 `reverse` 方法。 传入一个空字符串作为分隔符。
 
-Open up the console and see the output.

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```
+

+
+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+If the index is out of range, JavaScript will return `undefined`. Meaning that if you try to access `fruits[3]` in the above example, it will return `undefined`.
+

+
+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']
+```

+
+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+Now that you have a basic understanding about arrays, let's talk about loops. Loops are used to execute a block of code multiple times. One of those loops is the `while` loop. The `while` loop executes a block of code as long as the condition is true. The syntax of the `while` loop is as follows:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+To iterate over an array using a `for` loop, you can use the array's length property. For example, the following code snippet prints the elements of an array:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];
+for (let i = 0; i < arr.length; i++) {
+  console.log(arr[i]);

+Now that you know about the most common ways to iterate over values and arrays, there are a few more ways to iterate over arrays. Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
 
-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

-JavaScript is the programming language that powers the web. Unlike the HTML and CSS you have learned previously, JavaScript is most commonly used to write logic instead of markup.
+JavaScript es el lenguaje de programación que impulsa la web. A diferencia del HTML y CSS que has aprendido anteriormente, JavaScript se usa más comúnmente para escribir lógica en lugar de etiquetado.
 
-One of the most important concepts in programming is variables. A <dfn>variable</dfn> points to a specific memory address that stores a value. Variables are given a name which can be used throughout your code to access that value.
+Uno de los conceptos más importantes en la programación son las variables. Una <dfn>variable </dfn> apunta a una dirección de memoria específica que almacena un valor. A las variables se les asigna un nombre que puede ser usado a través de tu código para acceder a ese valor.
 
-Declaring a variable means giving it a name. In JavaScript, this is often done with the `let` keyword. For example, here is how you would declare a `hello` variable:
+Declarar una variable significa darle un nombre. En JavaScript, esto a menudo se hace con la palabra clave `let`. Por ejemplo, así es cómo declararías una variable `hola`:
 
 ```js
 let hello;
 ```
 
-Variable naming follows specific rules: names can include letters, numbers, dollar signs, and underscores, but cannot contain spaces and must not begin with a number.
+Debes serguir reglas específicas para nombrar una variable: los nombres pueden incluir letras, números, símbolo de dólar y guiones bajos, pero no pueden contener espacios y no deben comenzar con un número.
 
 Use the `let` keyword to declare a variable called `character`.
 
-_Note_: It is common practice to end statements in JavaScript with a semicolon. `;`
+_Nota_: Terminar las declaraciones en JavaScript con punto y coma es una práctica común. `;`

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+# --description--
+
+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.
+
+```js
+assert.lengthOf(code.match(/console\.log\(\s*cities\s*\)/g), 2);
+```

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```
+

+
+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+If the index is out of range, JavaScript will return `undefined`. Meaning that if you try to access `fruits[3]` in the above example, it will return `undefined`.
+
+

+
+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']

+
+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+Now that you have a basic understanding about arrays, let's talk about loops. Loops are used to execute a block of code multiple times. One of those loops is the `while` loop. The `while` loop executes a block of code as long as the condition is true. The syntax of the `while` loop is as follows:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+To iterate over an array using a `for` loop, you can use the array's length property. For example, the following code snippet prints the elements of an array:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];
+for (let i = 0; i < arr.length; i++) {

+Now that you know about the most common ways to iterate over values and arrays, there are a few more ways to iterate over arrays. Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

 A configuration of type $(a,b,c)$ is a graph thus built of $a$ units A and $b$ units B, where the graph's vertices are coloured using up to $c$ colours, so that no two adjacent vertices have the same colour. The compound graph above is an example of a configuration of type $(2,2,6)$, in fact of type $(2,2,c)$ for all $c ≥ 4$

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
 
-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.
 
 # --hints--
 
-Your `test` variable should come before your `return` keyword.
+Your `padRow` function should return the `test` variable.

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```

+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+If the index is out of range, JavaScript will return `undefined`. Meaning that if you try to access `fruits[3]` in the above example, it will return `undefined`.

+
+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']

+
+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+Now that you have a basic understanding about arrays, let's talk about loops. Loops are used to execute a block of code multiple times. One of those loops is the `while` loop. The `while` loop executes a block of code as long as the condition is true. The syntax of the `while` loop is as follows:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+To iterate over an array using a `for` loop, you can use the array's length property. For example, the following code snippet prints the elements of an array:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];
+for (let i = 0; i < arr.length; i++) {

Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

+One other useful array method is the `filter()` method. The `filter()` method creates a new array with all elements that pass the test implemented by the provided function. The syntax of the `filter()` method is as follows:
+
+```javascript
+const numbers = [2, 5, 6, 1, 9, -1]
+
+const newNumbers = numbers.filter((number) => {
+  return number > 2;
+});
+
+console.log(newNumbers); // Output: [5, 6, 9]
+```
+
+The `filter()` method creates a new array with all elements that are greater than 2. The `filter()` method does not change the original array.

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
 
-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.
 
 # --hints--

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.

+Before moving on, take a moment to review how functions work.
+
+Declare a function named `addTwoNumbers`. This function should take two arguments and return the sum of those two arguments.
+
+Then declare a `sum` variable and assign it the value of calling your `addTwoNumbers` function with `5` and `10` as the arguments. Log the `sum` variable to the console.
+
+
+# --hints--
+
+You should have a function called `addTwoNumbers`.
+
+```js
+assert.isFunction(addTwoNumbers);
+```
+
+Your function should return the sum of the two numbers.
+
+```js
+assert.strictEqual(addTwoNumbers(2,3), 5);
+```
+
+You should declare a `sum` variable.
+
+```js

+
+You should assign `sum` the value from calling the `addTwoNumbers` function with `5` and `10` for the arguments.
+
+```js

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```

+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+If the index is out of range, JavaScript will return `undefined`. Meaning that if you try to access `fruits[3]` in the above example, it will return `undefined`.

+
+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']

+
+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+
+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+To iterate over an array using a `for` loop, you can use the array's length property. For example, the following code snippet prints the elements of an array:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];
+for (let i = 0; i < arr.length; i++) {
+  console.log(arr[i]);
+}
+```

+
+Now that you know about the most common ways to iterate over values and arrays, there are a few more ways to iterate over arrays. Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

+One other useful array method is the `filter()` method. The `filter()` method creates a new array with all elements that pass the test implemented by the provided function. The syntax of the `filter()` method is as follows:
+
+```javascript
+const numbers = [2, 5, 6, 1, 9, -1]
+
+const newNumbers = numbers.filter((number) => {
+  return number > 2;
+});
+
+console.log(newNumbers); // Output: [5, 6, 9]
+```
+
+The `filter()` method creates a new array with all elements that are greater than 2. The `filter()` method does not change the original array.

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
 
-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+# --description--
+
+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.
+
+```js
+assert.lengthOf(code.match(/console\.log\(\s*cities\s*\)/g), 2);
+```

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```
+

+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript

+
+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']
+```

+
+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+Now that you have a basic understanding about arrays, let's talk about loops. Loops are used to execute a block of code multiple times. One of those loops is the `while` loop. The `while` loop executes a block of code as long as the condition is true. The syntax of the `while` loop is as follows:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+To iterate over an array using a `for` loop, you can use the array's length property. For example, the following code snippet prints the elements of an array:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];
+for (let i = 0; i < arr.length; i++) {
+  console.log(arr[i]);

+Now that you know about the most common ways to iterate over values and arrays, there are a few more ways to iterate over arrays. Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
 
-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

-A promise has three states: `pending`, `fulfilled`, and `rejected`. The promise you created in the last challenge is forever stuck in the `pending` state because you did not add a way to complete the promise. The `resolve` and `reject` parameters given to the promise argument are used to do this. `resolve` is used when you want your promise to succeed, and `reject` is used when you want it to fail. These are methods that take an argument, as seen below.

+이전 과제에서는 상위 타입(또는 부모) `Animal`로부터 동작을 상속받는 첫 번째 단계인 `Animal`의 새 인스턴스를 만드는 방법을 보았습니다.
 
-This challenge covers the next step: set the `prototype` of the subtype (or child)—in this case, `Bird`—to be an instance of `Animal`.
+이번 과제는 이 다음 단계에 대한 것입니다: 하위(혹은 자식)의 `prototype`인 `Bird`를 `Animal`의 인스턴스로 설정합니다.
 
 ```js
 Bird.prototype = Object.create(Animal.prototype);
 ```
 
-Remember that the `prototype` is like the "recipe" for creating an object. In a way, the recipe for `Bird` now includes all the key "ingredients" from `Animal`.
+`prototype`는 객체를 생성하는 레시피와 같다고 언급했습니다. `Bird`를 위한 조리법은 이제 `Animal`로부터 얻은 모든 중요 "재료"들을 포함한다고 할 수 있습니다.
 
 ```js
 let duck = new Bird("Donald");
 duck.eat();
 ```
 
-`duck` inherits all of `Animal`'s properties, including the `eat` method.
+`duck`은 `eat` 메소드를 포함한 `Animal`의 모든 속성을 상속 받습니다.
 
 # --instructions--
 
-Modify the code so that instances of `Dog` inherit from `Animal`.
+`Dog`의 인스턴스가 `Animal`로부터 상속받도록 코드를 수정하시오.
 
 # --hints--
 
-`Dog.prototype` should be an instance of `Animal`.
+`Dog.prototype`은 `Animal`의 인스턴스이어야 합니다.
 
 ```js
 assert(Animal.prototype.isPrototypeOf(Dog.prototype));

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+# --description--
+
+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.
+
+```js
+assert.lengthOf(code.match(/console\.log\(\s*cities\s*\)/g), 2);
+```

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```
+

+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+If the index is out of range, JavaScript will return `undefined`. Meaning that if you try to access `fruits[3]` in the above example, it will return `undefined`.
+

+
+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']

+
+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+Now that you have a basic understanding about arrays, let's talk about loops. Loops are used to execute a block of code multiple times. One of those loops is the `while` loop. The `while` loop executes a block of code as long as the condition is true. The syntax of the `while` loop is as follows:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+To iterate over an array using a `for` loop, you can use the array's length property. For example, the following code snippet prints the elements of an array:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];
+for (let i = 0; i < arr.length; i++) {

+Now that you know about the most common ways to iterate over values and arrays, there are a few more ways to iterate over arrays. Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

 A configuration of type $(a,b,c)$ is a graph thus built of $a$ units A and $b$ units B, where the graph's vertices are coloured using up to $c$ colours, so that no two adjacent vertices have the same colour. The compound graph above is an example of a configuration of type $(2,2,6)$, in fact of type $(2,2,c)$ for all $c ≥ 4$

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
 
-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.
 
 # --hints--

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.
+
+```js
+assert.lengthOf(code.match(/console\.log\(\s*cities\s*\)/g), 2);

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```
+

+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+If the index is out of range, JavaScript will return `undefined`. Meaning that if you try to access `fruits[3]` in the above example, it will return `undefined`.
+

+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']

+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+
+Now that you have a basic understanding about arrays, let's talk about loops. Loops are used to execute a block of code multiple times. One of those loops is the `while` loop. The `while` loop executes a block of code as long as the condition is true. The syntax of the `while` loop is as follows:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+
+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+To iterate over an array using a `for` loop, you can use the array's length property. For example, the following code snippet prints the elements of an array:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];
+for (let i = 0; i < arr.length; i++) {
+  console.log(arr[i]);
+}
+```

+
+Now that you know about the most common ways to iterate over values and arrays, there are a few more ways to iterate over arrays. Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

+One other useful array method is the `filter()` method. The `filter()` method creates a new array with all elements that pass the test implemented by the provided function. The syntax of the `filter()` method is as follows:
+
+```javascript

+
+const newNumbers = numbers.filter((number) => {

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.

The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.
 
 # --hints--
 
-Your `test` variable should come before your `return` keyword.
+Your `padRow` function should return the `test` variable.

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.

+Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (Strings, numbers, or other things).
+
+Arrays are a way to store multiple values in a single variable. They are a special type of object that has a length property and a series of numbered properties. Each numbered property is called an element, and each element can store a value of any type.
+
+An Example of an array is:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+```

+To access the elements of an array, you can use the index number. The index number starts from 0, so the first element of an array is at index 0, the second element is at index 1, and so on.
+
+For example, to access the first element of the `fruits` array, you can use the following code:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+If the index is out of range, JavaScript will return `undefined`. Meaning that if you try to access `fruits[3]` in the above example, it will return `undefined`.

+
+One of the most common ways to add a new element to an array is by using the `push()` method. The `push()` method adds one or more elements to the end of an array and returns the new length of the array.
+
+For example, to add a new element to the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+To remove the last element of an array, you can use the `pop()` method. The `pop()` method removes the last element from an array and returns that element.
+
+For example, to remove the last element from the `pet` array, you can use the following code:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();
+console.log(pet); // Output: ['cat', 'dog']

+
+One of the more complex methods used with arrays are the `splice()` and `slice()` methods. The `splice()` method changes the contents of an array by removing or replacing an element in the array. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from `begin` to `end` (`end` not included). The original array will not be modified.
+
+For example, to remove the second element from the `characters` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+The above element removes the second element from the `characters` array. The `splice()` method takes two arguments: the index of the element to remove and the number of elements to remove.
+
+
+To create a new array with the second element from the `character` array, you can use the following code:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+The above code creates a new array `newCharacters` with the second element from the `characters` array. The `slice()` method takes two arguments: the index of the element to start the slice and the index of the element to end the slice (not included).

+
+Now that you have a basic understanding about arrays, let's talk about loops. Loops are used to execute a block of code multiple times. One of those loops is the `while` loop. The `while` loop executes a block of code as long as the condition is true. The syntax of the `while` loop is as follows:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+The above code snippet initializes a variable `i` with the value `1`. The `while` loop executes the block of code as long as the value of `i` is less than or equal to `5`. The value of `i` is incremented by `1` in each iteration.

+The `for` loop is another type of loop that is used to execute a block of code multiple times. The `for` loop is used when the number of iterations is known. The syntax of the `for` loop is as follows:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+For example, the following code snippet prints the numbers from 1 to 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+To iterate over an array using a `for` loop, you can use the array's length property. For example, the following code snippet prints the elements of an array:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];

+
+Now that you know about the most common ways to iterate over values and arrays, there are a few more ways to iterate over arrays. Arrays have a built-in method called `map()`, which is used to create a new array by applying a function to each element of the original array. The `map()` method does not change the original array. The syntax of the `map()` method is as follows:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+The `map()` method creates a new array by applying the function `(arrayValue) => { return arrayValue * 2;` to each element of the original array. This is particularly useful when you want to transform the elements of an array without changing the original array.

+One other useful array method is the `filter()` method. The `filter()` method creates a new array with all elements that pass the test implemented by the provided function. The syntax of the `filter()` method is as follows:
+
+```javascript
+const numbers = [2, 5, 6, 1, 9, -1]
+
+const newNumbers = numbers.filter((number) => {
+  return number > 2;
+});
+
+console.log(newNumbers); // Output: [5, 6, 9]
+```
+
+The `filter()` method creates a new array with all elements that are greater than 2. The `filter()` method does not change the original array.

 A configuration of type $(a,b,c)$ is a graph thus built of $a$ units A and $b$ units B, where the graph's vertices are coloured using up to $c$ colours, so that no two adjacent vertices have the same colour. The compound graph above is an example of a configuration of type $(2,2,6)$, in fact of type $(2,2,c)$ for all $c ≥ 4$

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
 
-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

-The `:=` operator gives you the ability to assign variables in the middle of an expression. The syntax is: `name := val`, where `name` is the variable name and `val` is the variable value.
+Оператор `:=` дозволяє призначити змінні посеред виразу. Синтаксис такий: `name := val`, де `name` — назва змінної, а `val` — значення змінної.
 
-This construct is formally named *assignment expressions*, while the `:=` operator is commonly referred to as the *walrus* operator.
+Така конструкція формально називається *виразами присвоєння*, а оператор `:=` часто називають *оператором моржа*.
 
-Since you are going to need the `self.find_empty_cell()` call more than once, assign it to a variable `next_empty` by using the walrus operator. Then, enclose the assignment between a pair of parentheses.

Батьківські вузли - це ті, гілки яких ведуть до інших вузлів. Останні називаються дочірніми вузлами. Інші складніші сімейні терміни використовуються так, як цього й можна було очікувати. Піддеревом називаються всі нащадки певного вузла, гілки можуть ще зватися ребрами, а листові вузли - це кінцеві вузли дерева, які не мають дочірніх елементів. Нарешті, зверніть увагу, що дерева за своєю суттю є рекурсивними структурами даних. Тобто будь-які дочірні елементи вузла є одночасно батьківськими для власного піддерева і т. д. Важливо розуміти рекурсивний характер дерев при розробці алгоритмів для загальних операцій з цими структурами даних.

-To begin, we will discuss a particular type of tree, the binary tree. А точніше, ми розглянемо двійкове дерево пошуку. Опишімо його суть. В той час, як у деревоподібній структурі даних від одного вузла може відходити будь-яка кількість гілок, двійкове дерево може мати лише дві гілки для кожного вузла. Крім того, двійкове дерево пошуку впорядковане стосовно дочірніх піддерев таким чином, що значення кожного вузла в лівому піддереві є меншим за значення батьківського вузла, або ж рівним йому; а значення кожного вузла в правому піддереві є більшим від значення батьківського вузла чи рівним йому. Для кращого розуміння варто уявляти такий зв'язок:
+Для початку ми обговоримо конкретний тип дерева, а саме бінарне дерево. А точніше, ми розглянемо бінарне дерево пошуку. Опишемо його суть. В той час, як у деревоподібній структурі даних від одного вузла може відходити будь-яка кількість гілок, бінарне дерево може мати лише дві гілки для кожного вузла. Крім того, бінарне дерево пошуку впорядковане відповідно до дочірніх піддерев таким чином, що значення кожного вузла в лівому піддереві є меншим або дорівнює значенню батьківського вузла, а значення кожного вузла в правому піддереві є більшим або дорівнює значенню батьківського вузла. Щоб краще зрозуміти цей зв’язок, ось його візуалізація:

-Тепер цей впорядкований зв'язок легко помітити. Зверніть увагу, що кожне значення ліворуч від 8 (кореневого вузла) - менше за 8, а кожне значення праворуч - більше за 8. Також варто зауважити, що цей зв'язок стосується і кожного з піддерев. Наприклад, перший дочірній елемент зліва - це піддерево. 3 - це батьківська вершина, і, за правилами двійкових дерев пошуку, вона має рівно два дочірніх вузли. Ми вже знаємо, що лівий дочірній вузол цієї вершини (власне, як і кожен з його дочірніх елементів) буде меншим за 3, а правий дочірній вузол (так само як і кожен з його дочірніх елементів) буде більшим за 3 (але водночас меншим, ніж значення кореня структури) і т. д.

Зробімо так, щоб наше дерево не містило повторюваних значень. Якщо ми спробуємо додати значення, яке вже існує, метод повинен повернути `null`. Успішне додавання повернеться як `undefined`.

-Тепер, коли ми маємо загальне уявлення про двійкове дерево пошуку, поговорімо про нього більш детально. Двійкове дерево пошуку забезпечує логарифмічний час для виконання таких загальних операцій, як пошук, додавання і видалення, в середньому випадку складності та лінійний час у найгіршому випадку. Чому ж це так? Кожна з цих базових операцій передбачає знаходження елемента в дереві (або під час вставляння елемента - пошуку його місця в дереві). Деревоподібна структура є причиною того, що на кожному батьківському вузлі є ліве та праве розгалуження, а це дозволяє нам практично виключити з розгляду половину дерева, що залишилося. Як наслідок, пошук є пропорційним логарифму кількості вузлів в дереві, що забезпечує логарифмічний час виконання цих операцій у середньому випадку. А як тоді щодо найгіршого випадку? Що ж, розгляньте можливість створення дерева з таких значень, додаючи їх зліва направо: `10` `12`, `17`, `25`. Відповідно до правил двійкового дерева пошуку, ми додамо `12` праворуч від `10`, `17` праворуч від них і наостанок `25` - також праворуч. Тепер наше дерево нагадує зв'язаний список, і знаходження в ньому числа `25` передбачатиме лінійний обхід усіх елементів. Таким чином, у найгіршому випадку - лінійний час. Проблема тут в тому, що дерево не збалансоване. Ми розглянемо це детальніше в наступних завданнях.

-У даному завданні ми вивчимо геш-таблиці. Геш-таблицю використовують для реалізації асоціативних масивів або для зберігання пар (ключ, значення), як-от об'єкти та карти, які ми нещодавно вивчали. Як приклад, ми можемо внести об'єкт JavaScript у вигляді геш-таблиці (практична реалізація чого залежатиме від середовища запуску). Геш-таблиці функціонують таким чином: вони приймають вхідний ключ й конвертують його у числове значення визначеним шляхом. Згодом це числове значення використовується як дійсний ключ, за яким зберігається числове значення, що асоціюється з цим ключем. Якщо ви згодом захочете отримати доступ до того самого ключа ще раз, геш-функція опрацює ключ і поверне те саме числове значення, за допомогою якого можна знайти асоціативне значення. Тому цей процес є ефективним і час його виконання становить в середньому 0(1).
+У цьому завданні ми дізнаємось про хеш-таблиці.

-Геш-таблиці можна ще реалізувати у вигляді масивів, і тоді вони вираховуватимуть індекси за допомогою геш-функцій відповідно до заданого діапазону. У такому випадку визначення розміру масиву і сама геш-функція однаково важливі. А якщо геш-функція містить однакові значення для двох різних ключів? Що тоді? Такий випадок називається колізією (зіткненням). Як варіант, в такій ситуації можна зберегти обидві пари ключів-значень під одним індексом. Далі при пошуку кожної з них треба повторно переглянути всі елементи, щоб знайти потрібний ключ. Хороша геш-функція мінімізує колізії, щоб зберегти ефективний час пошуку.
+Хеш-таблиці можна реалізувати як масиви, для яких хеш-функції будуть генерувати індекси відповідно до заданого діапазону. Для цього методу важливо визначити розмір масиву, а також саму хеш-функцію.

-Далі ми відійдемо від вивчення двійкового дерева пошуку та розглянемо структуру іншого виду дерева пошуку під назвою префіксне. Префіксне дерево пошуку - це впорядкований вид дерева пошуку, який зазвичай містить рядки, досить часто дозволяє зберігати асоціативні масиви або динамічні сукупності даних, ключами яких є рядки. Їхньою перевагою є зберігання наборів даних у тих випадках, коли багато ключів мають однакові префікси, як-от усі слова у словнику. На відміну від двійкового дерева, вузли не пов'язані з реальними значеннями. Натомість шлях до вузла визначає певний ключ. До прикладу, якщо нам потрібно зберегти у префіксному дереві пошуку код у вигляді рядка, ми отримаємо чотири вузли, по одному на кожну букву: c — o — d — e. Застосовуючи цей шлях до всіх вузлів, ми отримаємо код у вигляді рядка, а сам шлях є ключем, який ми зберегли. Далі, якби ми хотіли додати рядкове кодування, він би розділив перші три вузли коду перед тим, як розгалузитись після d. У такому випадку, великий обсяг даних може зберігатися дуже компактно. Окрім цього, пошук може відбуватися дуже швидко, оскільки він практично обмежений довжиною рядка, який ми зберігаємо. А ще, на відміну від двійкових дерев вузол може зберігати будь-яку кількість дочірніх вузлів. Як можна було здогадатися із наведеного вище прикладу, деякі метадані зазвичай зберігаються у вузлах, які містять кінець ключа, тому під час наступних обходів дерева цей ключ все ще можна відновити. Скажімо, якби ми додали коди у зазначений вище приклад, нам потрібно було б якось дізнатися, що е в коді означає кінець введеного раніше ключа. В іншому випадку ця інформація буде втрачена при додаванні кодів.

А також він допоможе нам дізнатися, чи даний рядок містить слово з методом `isWord`, і вилучить всі слова, введені у префіксне дерево пошуку за допомогою способу `print`. `isWord` should return a boolean value and `print` should return an array of all these words as string values. Аби впевнитись, що ця структура даних реалізована правильно, ми задали структуру `Node` для кожного вузла у дереві. Кожен вузол буде об'єктом із властивістю `keys`, яка є об'єктом JavaScript Map. Він міститиме окремі літери, які виступають дійсними ключами кожного вузла. Також ми створили для вузлів властивість `end`, яка може бути налаштована як `true`, якщо вузол являє собою закінчення слова.

-Це, власне, перше з трьох завдань, де ми реалізуємо складнішу операцію у двійковому дереві пошуку, а саме - видалення. Операція "видалення" є складною, оскільки шляхом вилучення вузлів руйнуються зв'язки в дереві. Щоб переконатися, що структура двійкового дерева пошуку зберігається, ці зв'язки потрібно ретельно перевстановити. Деякі видалення передбачають зміни в дереві. Загалом є три випадки, з якими ви можете зіткнутися при видаленні вузлів: Листовий Вузол: Ціль видалення не має дочірніх елементів. Один дочірній елемент: Ціль видалення має лише один дочірній елемент. Два дочірніх елементи: Ціль видалення має два дочірніх елементи. Видалити листовий вузол легко: ми просто вилучаємо його. Видалити вузол з одним дочірнім елементом теж відносно легко: ми просто вилучаємо його та з'єднуємо батьківську вершину з дочірнім елементом вилученого вузла. Видалити ж вузол з двома дочірніми елементами трохи складніше, оскільки в такому разі потрібно з'єднати два дочірні вузли з батьківським деревом. Як саме впоратися з таким випадком, розглянемо у третьому завданні. Крім того, при видаленні варто пам'ятати про ребра. А що робити, якщо дерево порожнє? Чи якщо ціль видалення - кореневий вузол? Чи якщо дерево складається лише з двох елементів? Наразі зосередимося на першому випадку, тобто видаленні листового вузла.

-Створіть у нашому двійковому дереві метод під назвою `remove`. Тут побудуємо алгоритм для нашої операції видалення. Спершу в межах видалення створіть функцію, що знаходить той вузол, який ми хочемо видалити в поточному дереві. Якщо у дереві немає цього вузла, то метод `remove` повинен повернути `null`. Якщо цільовий вузол є листовим (без дочірніх елементів), то посилання на нього у батьківському елементі має бути `null`. Таким чином можемо вилучити вузол з дерева.

+Створіть метод під назвою `remove` на нашому бінарному дереві. У ньому ми будуватимемо логіку для операції видалення. Спочатку в межах `remove` створіть функцію, що знаходить той вузол, який ми хочемо видалити в поточному дереві. Якщо у дереві немає цього вузла, то метод `remove` має повернути `null`. Якщо цільовий вузол є листовим (без дочірніх елементів), то посиланням на нього у батьківському елементі має бути `null`. Таким чином можна видалити вузол з дерева.

-Оскільки ми вже навчилися видаляти листові вузли з дерева, то зараз розглянемо другий випадок: видалення вузла з одним дочірнім елементом. Скажімо, у нас задане дерево з вузлами 1 — 2 — 3, де 1 - це кореневий вузол. Щоб видалити вузол 2, нам потрібно з'єднати вершину 1 з вершиною 3. Тобто для того, щоб видалити вузол, який має лише один дочірній елемент, ми робимо так, аби батьківський вузол посилався на наступний вузол у дереві.

-До методу `remove` ми внесли певний код, який виконує задачі з останнього завдання. Ми знаходимо цільовий вузол для видалення, а також його батька, і визначаємо кількість дочірніх елементів нашого цільового вузла. Додамо наступний випадок для цільових вузлів з одним дочірнім елементом. Тепер нам доведеться визначити, на якій гілці знаходиться дочірній елемент: лівій чи правій. Після цього ми повинні встановити правильне посилання на цей вузол у батьківському елементі. Крім того, врахуємо такий випадок, коли ціль видалення є кореневим вузлом (це означає, що батьківський вузол буде `null`). Можете сміливо змінювати початковий код на свій власний, але перевіряйте, чи він успішно проходить тестування.

-Найважчим для реалізації є видалення вузлів, що мають два дочірні елементи. При видаленні такого вузла утворюються два піддерева, які більше не з'єднані з вихідною структурою дерева.

Як тільки така заміна виконана, замінений вузол повинен потрібно вилучити з правого піддерева. Та навіть ця операція є підступною, оскільки заміна може бути листовим вузлом або ж і навіть батьківським елементом правого піддерева.

-В останньому завданні ми описали ситуацію, коли двійкове дерево пошуку може стати незбалансованим. Щоб зрозуміти поняття балансу, розглянемо ще одну властивість дерева - його висоту. Висота дерева - це відстань від кореневого вузла до будь-якого заданого листового вузла. Різні шляхи в структурі дерева з великою кількістю гілок можуть мати неоднакову висоту. Однак для заданого дерева існує мінімальна та максимальна висота. Якщо дерево збалансоване, ці значення будуть відрізнятися максимум на одиницю. Це означає, що у збалансованому дереві всі листові вузли або існують в межах одного рівня; або, якщо це не так, відрізняються щонайбільше на один рівень.
+У попередньому завданні ми описали ситуацію, коли бінарне дерево пошуку може стати незбалансованим. Щоб зрозуміти поняття балансу, розглянемо ще одну властивість дерева: його висоту. Висота дерева — це відстань від кореневого вузла до будь-якого заданого листового вузла. Різні шляхи в структурі дерева з великою кількістю гілок можуть мати неоднакову висоту, однак для наданого дерева існує мінімальна та максимальна висота. Якщо дерево збалансоване, ці значення будуть відрізнятися максимум на одиницю. Це означає, що у збалансованому дереві всі листові вузли або існують в межах одного рівня, або, якщо вони на різних рівнях, відрізняються щонайбільше на один рівень.
 
-Як властивість двійкових дерев пошуку, баланс має велике значення, оскільки він визначає ефективність операцій у дереві. Згідно з поясненням в останньому завданні, незбалансовані дерева є для нас чи не найскладнішим викликом. Самозбалансовані двійкові дерева пошуку зазвичай використовуються для розв'язання цієї проблеми в деревах з динамічними наборами даних. До таких належать АВЛ-дерева, червоно-чорні дерева та Б-дерева. Усі ці типи дерев містять додатковий внутрішній алгоритм, що перебалансовує дерево тоді, коли вставка чи вилучення елементів призводять до порушення його балансу.
+Баланс важливий для дерев, оскільки саме він визначає ефективність операцій на дереві. Згідно з поясненням в попередньому завданні, через незбалансовані дерева виникає найгірша часова складність. З цієї причини до дерев з динамічними даними часто використовують самозбалансовані дерева. До таких належать АВЛ-дерева, червоно-чорні дерева та Б-дерева. Усі ці типи дерев містять додаткову внутрішню логіку, яка перебалансовує дерево, коли вставка чи видалення елементів призводять до порушення балансу.
 
-**Примітка:**Окрім висоти, двійкові дерева пошуку мають подібну властивість - глибину. Вона позначає відстань від кореня до даного вузла.

-Для нашого двійкового дерева напишіть два методи: `findMinHeight` and `findMaxHeight`. Ці методи повинні повернути ціле значення для мінімальної та максимальної висоти в заданому двійковому дереві відповідно. Якщо вузол порожній, присвоїмо йому висоту `-1` (базовий випадок). І, нарешті, додайте третій метод `isBalanced`, який повертається як `true` or `false` в залежності від того, збалансоване дерево чи ні. Щоб це визначити, можна застосувати перші два методи, які ви щойно написали.

-Тепер, коли ми можемо додавати та видаляти елементи, подивимось, для яких програм можна використовувати купи. Купи зазвичай використовуються для реалізації черг з пріоритетом, оскільки вони завжди зберігають елемент найбільшого чи найменшого значення на першій позиції. Крім того, їх застосовують для реалізації алгоритму сортування, який називається пірамідальне сортування. Тут ми побачимо, як реалізувати даний алгоритм. Пірамідальне сортування використовує неспадну купу, яка є протилежною до незростаючої купи. Неспадна купа завжди зберігає елемент з найменшим значенням в корені дерева (піраміди).

Структура неспадної купи гарантує, що у новому масиві вхідні елементи будуть розташовані від найменшого до найбільшого.

-А тепер перейдемо до іншої деревоподібної структури даних — двійкової купи. Двійкова купка — це частково впорядковане двійкове дерево, яке задовольняє властивість купи. Властивість купи визначає співвідношення між батьківським та дочірнім вузлами. Існує зростаюча купа, у якої всі батьківські вузли мають більше або рівне значення відносно дочірніх вузлів, та неспадна купа, де ця умова діє у зворотньому напрямку. Двійкові купи — це ще також повні двійкові дерева. Це означає, що всі рівні дерева повністю заповнені або, якщо останній рівень неповний, він заповнений зліва направо.
+А тепер перейдемо до іншої деревоподібної структури даних — бінарної купи. Бінарна купа — це частково впорядковане бінарне дерево, яке задовольняє властивість купи. Властивість купи визначає зв’язок між батьківським та дочірнім вузлами. Купа може бути незростаючою (значення всіх батьківських вузлів більше або дорівнює значенню дочірніх вузлів) та неспадною (навпаки). Бінарні купи — це також повні бінарні дерева. Це означає, що всі рівні дерева повністю заповнені або, якщо останній рівень неповний, воно заповнене зліва направо.
 
-І хоч двійкові купи реалізуються у вигляді дерева з вузлами, що ростуть уліво та вправо, відповідно до властивості купи вона може бути представлена масивом, за умови часткового впорядкування. Нас цікавить співвідношення батьківський-дочірній вузол, а з допомогою простої арифметики ми зможемо обрахувати кількість дочірних елементів певного батьківського вузла та батьків конкретного дочірнього вузла.

+Наприклад, розглянемо наступну бінарну неспадну купу у вигляді масиву:

 ```
 
-Перший елемент — кореневий вузол — `6`. Його дочірні вузли — `22` та `30`. Якщо поглянути на відношення між індексами масиву цих значень, то для індексу `i` дочірніми вузлами будуть `2 * i + 1` and `2 * i + 2`. Схожим чином елемент в індексі `0` буде мати батьківське відношення стосовно цих двох дочірніх вузлів в індексі `1` і `2`. Загалом можна знайти батьківський вузол у будь-якому індексі, використовуючи такий шаблон: `Math.floor((i - 1) / 2)`. За ним можна отримувати правдиву інформацію незалежно від розміру дерева. На завершення, ми можемо зробити незначне коригування, щоб полегшити обчислення, пропустивши перший елемент у рядку. Ця дія створює зв'язки з кожним елементом із заданим індексом `i`:

На відміну від пошуку в глибину, пошук у ширину відвідує всі вузли на даному рівні дерева, а потім переходить до наступного.

-У цьому методі ми спочатку додаємо кореневий вузол до черги. Потім починаємо цикл, в якому перший елемент черги вилучається, додається до нового масиву, а тоді перевіряються обидва дочірні піддерева. Якщо дочірні елементи не є нулями (null), то вони додаються до черги. Цей процес повторюється, допоки черга не стає порожньою.

-Нам уже відомо, як у двійковому дереві пошуку знайти певне значення. А якщо ми хочемо обійти дерево повністю? Або якщо нам потрібно просто знайти якесь значення, але при цьому ми не маємо впорядкованого дерева? Саме тому ми познайомимо вас з деякими методами обходу дерева, які використовуються для дослідження деревоподібних структур даних. Спершу розглянемо пошук у глибину. Цей метод дозволяє дослідити дане піддерево настільки глибоко, наскільки це можливо, перед тим, як продовжити пошук на іншому піддереві. Пошук може здійснюватися трьома різними способами. Серединний порядок (inorder): з крайнього лівого вузла до крайнього правого вузла. Прямий порядок (pre-order): обхід всіх кореневих, а потім листових вузлів. Зворотний порядок (post-order): обхід всіх листових, а потім кореневих вузлів. Нескладно здогадатися, що можна обирати різні пошукові методи залежно від того, які дані зберігає дерево і що ви шукаєте. Для двійкового дерева пошуку серединний обхід повертає вузли у сортованому порядку.

-Уявіть, що ви стоїте у лінії конга. Ви кладете руки на плечі людини, що стоїть перед вами, а людина позаду вас кладе руки на ваші плечі. Ви бачите її, але вона ж перешкоджає тому, щоб ви побачили й тих, хто стоїть попереду неї у цій лінії. Ця людина попереду вас знає, хто вона сама, може побачити лише наступну людину в лінії, але не знає про існування інших людей попереду чи позаду. Так само і вузол.
+Уявіть, що ви стоїте в колоні. Ви кладете руки на плечі людини, що стоїть перед вами, а людина позаду вас кладе руки на ваші плечі. Ви бачите людину перед собою, але вона заступає інших. Так само і вузол: він знає, чим є, але може бачити лише наступний елемент і не знає про існування інших.

-There is a bit of a problem, here. Your `test` declaration is currently after your `return` statement. An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your function code. This means that any code after a `return` statement will not run.
+Values returned out of a function are used by calling the function. You can use the function call directly as the value it returns, or capture the returned value in a variable. This way, you can use the value assigned to a locally scoped variable, outside the function it was created in.
+
+```js
+function getName() {
+  const name = "Camper cat";
+  return name;
+}
+
+console.log(getName()); // "Camper cat"
+
+const capturedReturnValue = getName();
+console.log(capturedReturnValue); // "Camper cat"
+
+console.log(name); // reference error
+```
+
+To use your `"Testing"` value, return it out of the `padRow` function by updating your `return` statement to return only the `test` variable.
 
-Move your `test` initialization to the line above your `return` statement.

-If you try to add a `console.log(test)` call below your `padRow` function, you would see an error. This is because `test` is defined in the local scope, meaning you cannot access it in the global scope (outside of the `padRow` function).
+Below the `return` statement, log the string `"This works!"` to the console.
 
-Returning a value from a function brings that value into the scope where the function was called. To bring your `"Testing"` value from the `padRow` function into the global scope, update your `return` statement to return only the `test` variable.
+After doing that, you will see that the string `"This works!"` does not display in the console, and the `console.log("This works!")` line is greyed out.
+
+Copy the console log and paste it above the `return` statement. Now, the string `"This works!"` should appear in the console.
+
+An important thing to know about the `return` keyword is that it does not just define a value to be returned from your function, it also stops the execution of your code inside a function or a block statement. This means any code after a `return` statement will not run.

+# --description--
+
+In the last few steps, you learned all about working with arrays. Take a moment to review what you have learned.
+
+Start by declaring a `cities` variable and initializing it as an array of the strings `"London"`, `"New York"`, and `"Mumbai"`. Then log that variable to the console.
+
+After logging, change the last element of `cities` to the string `"Mexico City"`, then log the `cities` variable again.
+
+When done correctly, you should see this output in the console.
+
+```js
+[ "London", "New York", "Mumbai" ]
+[ "London", "New York", "Mexico City" ]
+```
+
+# --hints--
+
+You should use `let` to declare a `cities` variable.
+
+```js
+assert.match(code, /let\s+cities/);
+```
+
+You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
+
+```js
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+```
+
+You should use `console.log()` to log the entire `cities` array to the console.
+
+```js
+assert.match(code, /console\.log\(\s*cities\s*\)/);
+```
+
+You should update the last element of the `cities` array to the string `"Mexico City"`. Remember that you can access the last element of an array using `array[array.length - 1]`.
+
+```js
+assert.deepEqual(cities, ["London", "New York", "Mexico City"]);
+```
+
+You should have two `console.log(cities)` statements in your code.
+
+```js
+assert.lengthOf(code.match(/console\.log\(\s*cities\s*\)/g), 2);
+```

+Рядки та числа можна вважати будівельними блоками. А оскільки скрипти стають все складнішими, вам доведеться справлятись з великою кількістю цих блоків. На щастя, JavaScript має декілька типів даних для цього. Масив — це впорядкована колекція елементів (рядків, чисел та багато іншого).
+
+Завдяки масивам можна зберігати декілька значень в одній змінній. Це спеціальний тип об’єкта, який має властивість довжини та декілька пронумерованих властивостей. Пронумеровану властивість називають елементом, а кожен елемент може зберігати значення будь-якого типу.

+Щоб отримати елементи масиву, можна використати індекс. Індекси починаються з 0, тому перший елемент масиву розташований за індексом 0, другий — за індексом 1 і так далі.
+
+Наприклад, щоб отримати перший елемент масиву `fruits`, можна використати такий код:
+
+```javascript
+const fruits = ['apple', 'banana', 'orange'];
+console.log(fruits[0]); // Output: apple
+console.log(fruits[2]); // Output: orange
+```
+
+Якщо індекс поза діапазоном, JavaScript поверне `undefined`. Якби ви спробували отримати `fruits[3]` у прикладі вище, він би повернув `undefined`.

+Найпоширеніший спосіб додати новий елемент до масиву — використати метод `push()`. Метод `push()` додає один чи більше елементів в кінець масиву та повертає масив нової довжини.
+
+Наприклад, щоб додати новий елемент до масиву `pet`, можна використати такий код:
+
+```javascript
+const pet = ['cat', 'dog', 'bunny'];
+pet.push('parrot');
+console.log(pet); // Output: ['cat', 'dog', 'bunny', 'parrot']
+```
+
+Щоб видалити останній елемент масиву, використовують метод `pop()`. Метод `pop()` видаляє останній елемент з масиву та повертає цей елемент.
+
+Наприклад, щоб видалити останній елемент з масиву `pet`, можна використати такий код:
+
+```javascript
+const pet = ['cat', 'dog', 'tiger'];
+pet.pop();

+Одними з найскладніших методів, які використовують з масивами, є `splice()` та `slice()`. Метод `splice()` змінює вміст масиву, видаляючи або замінюючи елемент в масиві. Метод `slice()` повертає поверхневу копію частини масиву від `begin` до `end` (не включаючи `end`) у вигляді нового об’єкту. Вхідний масив не змінюється.
+
+Наприклад, щоб видалити другий елемент з масиву `characters`, можна використати такий код:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+characters.splice(1, 1);
+console.log(characters); // Output: ['Harry', 'Hermione']
+```
+
+У прикладі вище видалено другий елемент з масиву `characters`. Метод `splice()` приймає два аргументи: індекс елемента, який потрібно видалити, та кількість елементів, які потрібно видалити.
+
+
+Щоб створити новий масив з другим елементом масиву `character`, можна використати такий код:
+
+```javascript
+const characters = ['Harry', 'Ron', 'Hermione'];
+const newCharacters = characters.slice(1, 2);
+console.log(newCharacters); // Output: ['Ron']
+```
+
+У прикладі вище створено новий масив `newCharacters`, який містить другий елемент з масиву `characters`. Метод `slice()` приймає два аргументи: індекс елемента, з якого починається розріз, та індекс елемента, де розріз закінчується (його не включено).

+
+Тепер у вас є базові знання щодо масивів, тому поговоримо про цикли. Цикли використовують, щоб виконати блок коду декілька разів. Одним з таких циклів є `while`. Цикл `while` виконує блок коду доки виконується умова. Синтаксис циклу `while` такий:
+
+```javascript
+while (condition) {
+  // code block to be executed
+}
+```
+
+Наприклад, наведений нижче фрагмент коду друкує числа від 1 до 5:
+
+```javascript
+let i = 1;
+while (i <= 5) {
+  console.log(i);
+  i++;
+}
+```
+
+У прикладі вище змінній `i` надано значення `1`. Цикл `while` виконує блок коду, якщо значення `i` менше або дорівнює `5`. Значення `i` збільшується на `1` кожної ітерації.

+
+Цикл `for` — ще один тип циклу, який використовують для виконання блоку коду декілька разів. Цикл `for` використовують, якщо відома кількість ітерацій. Синтаксис циклу `for` такий:
+
+```javascript
+for (initialization; condition; increment/decrement) {
+  // code block to be executed
+}
+```
+
+Наприклад, наведений нижче фрагмент коду друкує числа від 1 до 5:
+
+```javascript
+for (let i = 1; i <= 5; i++) {
+  console.log(i);
+}
+```
+
+Щоб ітерувати над масивом за допомогою методу `for`, можна використати властивість довжини масиву. Наприклад, наведений нижче фрагмент коду надрукує елементи масиву:
+
+```javascript
+const arr = [1, 2, 3, 4, 5];
+for (let i = 0; i < arr.length; i++) {
+  console.log(arr[i]);

+
+Ви вже знаєте про найпоширеніші способи ітерувати над значеннями та масивами, тому розглянемо й інші способи ітерації над масивами. Масиви мають вбудований метод під назвою `map()`, який використовують для створення нового масиву, застосовуючи функцію до кожного елемента вхідного масиву. Метод `map()` не змінює вхідний масив. Синтаксис методу `map()` такий:
+
+```javascript
+const array = [1, 2, 3, 4, 5];
+
+const newArray = array.map((arrayValue) => {
+  return arrayValue * 2;
+});
+
+console.log(newArray); // Output: [2, 4, 6, 8, 10]
+```
+
+Метод `map()` створює новий масив, застосовуючи функцію `(arrayValue) => { return arrayValue * 2;` до кожного елемента вхідного масиву. Це особливо корисно, якщо потрібно змінити елементи масиву, не змінюючи вхідний масив.

+
+`filter()` — ще один корисний метод масиву. Метод `filter()` створює новий масив з усіх елементів, які проходять тест, реалізований наданою функцією. Синтаксис методу `filter()` такий:
+
+```javascript
+const numbers = [2, 5, 6, 1, 9, -1]
+
+const newNumbers = numbers.filter((number) => {
+  return number > 2;
+});
+
+console.log(newNumbers); // Output: [5, 6, 9]
+```
+
+Метод `filter()` створює новий масив з усіма елементами, які більші за 2. Метод `filter()` не змінює вхідний масив.

 This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
 
-A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+A clause is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
 
 The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
 
-For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.
