# --description--
|
|
|
|
In the last challenge, you learned to use the caret character to search for patterns at the beginning of strings. There is also a way to search for patterns at the end of strings.
|
|
|
|
You can search the end of strings using the dollar sign character `$` at the end of the regex.
|
|
|
|
```js
|
|
let theEnding = "This is a never ending story";
|
|
let storyRegex = /story$/;
|
|
storyRegex.test(theEnding);
|
|
let noEnding = "Sometimes a story will have to end";
|
|
storyRegex.test(noEnding);
|
|
```
|
|
|
|
The first `test` call would return `true`, while the second would return `false`.
|
|
|
|
# --instructions--
|
|
|
|
Use the anchor character (`$`) to match the string `caboose` at the end of the string `caboose`.
|
|
|
|
# --hints--
|
|
|
|
You should search for `caboose` with the dollar sign `$` anchor in your regex.
|
|
|
|
```js
|
|
assert(lastRegex.source == 'caboose$');
|
|
```
|
|
|
|
Your regex should not use any flags.
|
|
|
|
```js
|
|
assert(lastRegex.flags == '');
|
|
```
|
|
|
|
You should match `caboose` at the end of the string `The last car on a train is the caboose`
|
|
|
|
```js
|
|
assert(lastRegex.test('The last car on a train is the caboose'));
|
|
```
|
|
|
|

let caboose = "The last car on a train is the caboose";

let result = lastRegex.test(caboose);
|
|
```

let caboose = "The last car on a train is the caboose";

let lastRegex = /caboose$/; // Change this line
|
|
let result = lastRegex.test(caboose);
