--description--

Sometimes whitespace characters around strings are not wanted but are there. Typical processing of strings is to remove the whitespace at the start and end of it.

--instructions--

Write a regex and use the appropriate string methods to remove whitespace at the beginning and end of strings.

Note: The String.prototype.trim() method would work here, but you'll need to complete this challenge using regular expressions.

--hints--

result should be equal to the string Hello, World!

assert(result === 'Hello, World!');

Your solution should not use the String.prototype.trim() method.

assert(!__helpers.removeJSComments(code).match(/\.?[\s\S]*?trim/));

The result variable should not directly be set to a string

assert(!__helpers.removeJSComments(code).match(/result\s*=\s*["'`].*?["'`]/));

The value of the hello variable should not be changed.

assert(hello === '   Hello, World!  ');

--seed--

--seed-contents--

let hello = "   Hello, World!  ";
let wsRegex = /change/; // Change this line
let result = hello; // Change this line

--solutions--

let hello = "   Hello, World!  ";
let wsRegex = /^(\s+)(.+[^\s])(\s+)$/;
let result = hello.replace(wsRegex, '$2');
