Remove Whitespace from Start and End (using capture group)

Tell us what’s happening:

Why doesnt it work?

I believed that my solution was following like this:

  1. caret stands for start
  2. (one or more white spaces)
  3. repeat capture group
    4)at the end

Your code so far

let hello = "   Hello, World!  ";
let wsRegex = /^(\s+)\1$/; // Change this line
let result = hello.replace(wsRegex, "0"); // Change this line

Link to the challenge:

your regex match a string of only spaces - maybe rethink a bit on what you want to match

Your replace also has a zero (“0”) as the replacement?

yes, just to be able to see what is taking spaces off.
