+
+To begin, create a variable named `fccSentence` and assign it the string `"freeCodeCamp is a great place to learn web development."`.
+
+# --hints--
+
+You should declare a variable named `fccSentence`.
+
+```js

+
+Your `fccSentence` variable should be a string.

+
+Your `fccSentence` variable should be assigned the string `"freeCodeCamp is a great place to learn web development."`.

+
+As you recall from the prior lessons, the `includes()` method checks if a string contains a specific substring and returns `true` or `false`.
+
+Here is an example using the `includes()` method:
+
+```js
+const text = "Hello World";
+const hasHello = text.includes("Hello");
+console.log(hasHello); // true
+```
+
+Create a variable named `hasFreeCodeCamp`. Then assign it the result of using the `includes()` method on `fccSentence` to check if it contains `"freeCodeCamp"`.
+
+# --hints--
+
+You should declare a variable named `hasFreeCodeCamp`.
+
+```js
+assert.exists(hasFreeCodeCamp);
+```
+
+You should use `fccSentence.includes("freeCodeCamp")`.
+
+```js
+assert.match(__helpers.removeJSComments(code), /fccSentence\.includes\(\s*(['"`])freeCodeCamp\1\s*\)/);
+```
+
+You should assign the result of `fccSentence.includes("freeCodeCamp")` to your `hasFreeCodeCamp` variable.
+
+```js
+assert.match(__helpers.removeJSComments(code), /hasFreeCodeCamp\s*=\s*fccSentence\.includes\(\s*(['"`])freeCodeCamp\1\s*\)/);

+

+The `slice()` method extracts a section of a string. It takes two arguments: the start index (included) and the end index (not included).
+
+Here is an example:
+
+```js
+const greeting = "Hello World";
+const firstWord = greeting.slice(0, 5);
+console.log(firstWord); // "Hello"
+```
+
+String indices start at 0. In the `message` string, the character at index 11 is `f` (the start of "freeCodeCamp").
+
+Create a variable named `platform`. Then assign it the result of using `message.slice(11, 23)` to extract `"freeCodeCamp"`.
+
+# --hints--

+
+The `slice()` method can use negative indices to count from the end of the string. `-1` refers to the last character.
+
+Here is an example:
+
+```js
+const text = "JavaScript";
+const lastThree = text.slice(-3);
+console.log(lastThree); // "ipt"
+```
+
+Create a variable named `endPunctuation`. Then assign it the result of using `message.slice(-1)` to extract the last character.
+
+Then use either a template literal or string concatenation to log the message `The ending punctuation mark is a "<endPunctuation>"` to the console. Replace `<endPunctuation>` with the actual value of the variable.
+
+# --before-each--
+
+```js
+const spy = __helpers.spyOn(console, 'log');
+```
+
+# --hints--
+
+You should declare a variable named `endPunctuation`.
+
+```js
+assert.exists(endPunctuation);
+```
+
+Your `endPunctuation` variable should be a string.
+
+```js
+assert.isString(endPunctuation);
+```
+
+You should use `message.slice(-1)`.
+
+```js
+assert.match(__helpers.removeJSComments(code), /message\.slice\(\s*-1\s*\)/);
+```
+
+You should assign the result of `message.slice(-1)` to your `endPunctuation` variable.
+
+```js
+assert.match(__helpers.removeJSComments(code), /endPunctuation\s*=\s*message\.slice\(\s*-1\s*\)/);
+```
+
+Your `endPunctuation` variable should equal `"!"`.
+
+```js
+assert.strictEqual(endPunctuation, "!");
+```
+
+You should log the message `The ending punctuation mark is a "<endPunctuation>"`, where `<endPunctuation>` should be replaced with the actual value of the variable.
+
+```js
+assert.deepInclude(spy.calls, ['The ending punctuation mark is a "!"']);
+```
