--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$/;
storyRegex.test(theEnding);
let noEnding = "Sometimes a story will have to end";
storyRegex.test(noEnding);
The first test
call would return true
, while the second would return false
.
--instructions--
Use the anchor character ($
) 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.
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
lastRegex.lastIndex = 0;
assert(lastRegex.test('The last car on a train is the caboose'));

--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);
