To finish this challenge, it's necessary to use __boundaries__.
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
The __$__ Matches end of input.
For example, /t$/ does not match the "t" in "eater", but does match it in "eat".
__important:__ If the multiline flag is set to true, also matches immediately before a line break character.
### Spoiiler Alert: Solution ahead
```javascript
let caboose = "The last car on a train is the caboose";
let lastRegex = /caboose$/; // Change this line
let result = lastRegex.test(caboose);
```
