--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.

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

--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.

assert(lastRegex.source == 'caboose$');

Your regex should not use any flags.

assert(lastRegex.flags == '');

You should match "caboose" at the end of the string "The last car on a train is the caboose"

assert(lastRegex.test('The last car on a train is the caboose'));

--seed--

--seed-contents--

let caboose = "The last car on a train is the caboose";
let lastRegex = /change/; // Change this line
let result = lastRegex.test(caboose);

--solutions--

let caboose = "The last car on a train is the caboose";
let lastRegex = /caboose$/; // Change this line
let result = lastRegex.test(caboose);
