|
||||
The `sort()` method converts elements of an array into strings and sorts them based on their `UTF-16` code units values.
|
||||
In earlier steps, you learned how to work with the `sort()` method to sort the songs in alphabetical order. Another use case for the callback function is to randomize an array.
|
||||
|
||||
One way to randomize an array of items would be to subtract `0.5` from `Math.random()` which produces random values that are either positive or negative. This makes the comparison result a mix of positive and negative values, leading to a random ordering of elements.
|
||||
|
||||
```js
|
||||
const numbers = [4, 2, 5, 100, 1, 3];
|
||||
|
||||
numbers.sort();
|
||||
console.log(numbers); // Output: [1, 100, 2, 3, 4, 5]
|
||||
const names = ["Tom", "Jessica", "Quincy", "Naomi"];
|
||||
names.sort(() => Math.random() - 0.5);
|
||||
```
|
||||
|
||||
You can see `100` comes right after 1, which is not supposed to happen. This is a default behavior of the `sort()` method you can fix by passing in a callback this way:
|
||||
Use the `sort()` method on the `userData?.songs` array. Pass a callback to the method, and return the result of `Math.random() - 0.5`.
|
||||
|
||||
```js
|
||||
const numbers = [4, 2, 5, 100, 1, 3];
|
||||
|
||||
numbers.sort((a, b) => a - b);
|
||||
console.log(numbers); // Output: [1, 2, 3, 4, 5, 100]
|
||||
```
|
||||
|
||||
Use the `sort()` method on the `userData?.songs` array. For the callback, introduce `Math.random()`, and subtract `0.5`.

Now that you have the list of songs displayed on the screen, it would be nice to sort them in alphabetical order by title. You could manually update the `allSongs` array, but JavaScript has an array method you can use called <dfn>sort()</dfn>.
|
||||
|
||||
The `sort()` method converts elements of an array into strings and sorts them in place based on their values in the `UTF-16` encoding.
|
||||
|
||||
```js
|
||||
const names = ["Tom", "Jessica", "Quincy", "Naomi"];
|
||||
names.sort() // ["Jessica", "Naomi", "Quincy", "Tom"]
|
||||
```
|
||||
|
||||
Add the `sort()` method to `userData?.songs`.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should add the `sort()` method to `userData?.songs`.
|
||||
|
||||
```js
|
||||
assert.match(code, /userData\?\.songs\.sort\(*.\);?/);
|
||||
```

# --description--

|

To sort the songs in alphabetical order by title, you will need to pass in a compare callback function into your `sort()` method.
|
||||
|
||||
Here is an example of sorting a list of fruits by name.
|
||||
|
||||
```js
|
||||
const fruits = [
|
||||
{ name: "Apples", price: 0.99 },
|
||||
{ name: "Blueberries", price: 1.49 },
|
||||
{ name: "Grapes", price: 2.99 },
|
||||
];
|
||||
|
||||
fruits.sort((a, b) => {
|
||||
if (a.name < b.name) {
|
||||
return -1;
|
||||
}
|
||||
|
||||
if (a.name > b.name) {
|
||||
return 1;
|
||||
}
|
||||
|
||||
return 0;
|
||||
});
|
||||
```
|
||||
|
||||
In the next few steps, you will learn what each of those `if` statements is doing inside that callback function. But for now, add an empty callback function to your `sort()` method and use `a` and `b` for the parameter names.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should have an empty callback function `()=>{}` inside your `sort()` method with `a` and `b` for the parameter names.
|
||||
|
||||
```js
|
||||
assert.match(code, /userData\?\.songs\.sort\(\s*\(\s*a\s*,\s*b\s*\)\s*=>\s*{\s*}\s*\);?/);
|
||||
```

# --description--
|
||||
|
||||
The `sort()` method accepts a compare callback function that defines the sort order.
|
||||
|
||||
In this example, the first condition `(a.name < b.name)` checks if the name of the first fruit is less than the name of the second fruit. If so, the first fruit is sorted before the second fruit.
|
||||
|
||||
Strings are compared lexicographically which means they are compared character by character. For example, `"Apples"` is less than `"Bananas"` because `"A"` comes before `"B"` in the alphabet.
|
||||
|
||||
The reason why this example is returning numbers is because the `sort()` method is expecting a number to be returned. If you return a negative number, the first item is sorted before the second item.
|
||||
|
||||
```js
|
||||
const fruits = [
|
||||
{ name: "Apples", price: 0.99 },
|
||||
{ name: "Blueberries", price: 1.49 },
|
||||
{ name: "Grapes", price: 2.99 },
|
||||
];
|
||||
|
||||
fruits.sort((a, b) => {
|
||||
if (a.name < b.name) {
|
||||
return -1;
|
||||
}
|
||||
|
||||
if (a.name > b.name) {
|
||||
return 1;
|
||||
}
|
||||
|
||||
return 0;
|
||||
});
|
||||
```
|
||||
|
||||
Inside your callback function, add an `if` statement to check if `a.title` is less than `b.title`. If so, return `-1`.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should have an `if` statement inside your callback function.
|
||||
|
||||
```js
|
||||
assert.match(code, /if\s*\(/);
|
||||
```
|
||||
|
||||
Your `if` statement should check if `a.title` is less than `b.title`.
|
||||
|
||||
```js
|
||||
assert.match(code, /if\s*\(\s*a\.title\s*<\s*b\.title\s*\)/);
|
||||
```
|
||||
|
||||
Your `if` statement should return `-1` if `a.title` is less than `b.title`.
|
||||
|
||||
```js
|
||||
assert.match(code, /if\s*\(\s*a\.title\s*<\s*b\.title\s*\)\s*{\s*return\s*-1;?\s*}|if\s*\(\s*a\.title\s*<\s*b\.title\s*\)\s*return\s*-1;?/);
|
||||

# --description--
|

|

The second condition in this example checks if `a.name > b.name`. If so, the function returns `1`, which sorts the first fruit after the second fruit.
|
||||
|
||||
```js
|
||||
const fruits = [
|
||||
{ name: "Apples", price: 0.99 },
|
||||
{ name: "Blueberries", price: 1.49 },
|
||||
{ name: "Grapes", price: 2.99 },
|
||||
];
|
||||
|
||||
fruits.sort((a, b) => {
|
||||
if (a.name < b.name) {
|
||||
return -1;
|
||||
}
|
||||
|
||||
if (a.name > b.name) {
|
||||
return 1;
|
||||
}
|
||||
|
||||
return 0;
|
||||
});
|
||||
```
|
||||
|
||||
Inside your callback function, add another `if` statement to check if `a.title` is greater than `b.title`. If so, return the number `1`.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should have an `if` statement inside your callback function.
|
||||
|
||||
```js
|
||||
assert.match(code, /if\s*\(/);
|
||||
```
|
||||
|
||||
Your `if` statement should check if `a.title` is greater than `b.title`.
|
||||
|
||||
```js
|
||||
assert.match(code, /if\s*\(\s*a\.title\s*>\s*b\.title\s*\)/);
|
||||
```
|
||||
|
||||
Your `if` statement should return the number `1` if `a.title` is greater than `b.title`.
|
||||
|
||||
```js
|
||||
assert.match(code, /if\s*\(\s*a\.title\s*>\s*b\.title\s*\)\s*{\s*return\s*1;?\s*}|if\s*\(\s*a\.title\s*>\s*b\.title\s*\)\s*return\s*1;?/);
|
||||

In the example, if `a.name` is equal to `b.name`, then the function returns `0`. This means that nothing changes and the order of `a` and `b` remains the same.
|
||||
|
||||
```js
|
||||
const fruits = [
|
||||
{ name: "Apples", price: 0.99 },
|
||||
{ name: "Blueberries", price: 1.49 },
|
||||
{ name: "Grapes", price: 2.99 },
|
||||
];
|
||||
|
||||
fruits.sort((a, b) => {
|
||||
if (a.name < b.name) {
|
||||
return -1;
|
||||
}
|
||||
|
||||
if (a.name > b.name) {
|
||||
return 1;
|
||||
}
|
||||
|
||||
return 0;
|
||||
});
|
||||
```
|
||||
|
||||
Below your `if` statements, return the number `0` to leave the order of the two elements unchanged.
|
||||
|
||||
Now you should see the songs in alphabetical order in the playlist.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should return the number `0` below your `if` statements.
|
||||
|
||||
```js
|
||||
assert.match(code, /return\s+0\s*;?/);
|
||||
