## Description
|
|
<section id='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 <code>$</code> at the end of the regex.
|
|
|
|
```js
|
|
let theEnding = "This is a never ending story";
|
|
let storyRegex = /story$/;
|
|
storyRegex.test(theEnding);
|
|
// Returns true
|
|
let noEnding = "Sometimes a story will have to end";
|
|
storyRegex.test(noEnding);
|
|
// Returns false
|
|
|
|
```
|

|
|
testString: assert(lastRegex.source == "caboose$");
|
|
- text: Your regex should not use any flags.
|
|
testString: assert(lastRegex.flags == "");
|
|
- text: You should match <code>"caboose"</code> at the end of the string <code>"The last car on a train is the caboose"</code>
|
|
testString: assert(lastRegex.test("The last car on a train is the caboose"));
