Tell us what’s happening:

Your code so far


let hello = "   Hello, World!  ";
let wsRegex = /^\s.*$\s/g; // Change this line
let result = hello.replace(wsRegex,""); // Change this line
console.log(result);

So, what’s happening? What else have you tried?

What did you expect to work that didn’t?

Noone’s going to try to help if we don’t know these things

is this part correct? I would have thought you want to search for space at the end like this:
\s$

I have tried this but I want fewer lines than this which I was not able to get

let hello = "   Hello, World!  ";
let wsRegex = /^(\s+)/g;
let result = hello.replace(wsRegex,"");
let wsRegex1 = /(\s+)$/g;
result = result.replace(wsRegex1,"");
console.log(result);

You can chain the functions and put the regex directly in the functions, though there’s nothing wrong with a 4 line function
