***Would not let me delete post but I found the issue

Hello,

I am a little confused as to why my solution does not work for this problem. I am not clear as to why the ending spaces are not being replaced as well.

My code produces : "Hello, World! " (Spaces remain on the end of string).

Any insight would be appreciated!

Your code so far

let hello = "   Hello, World!  ";
let wsRegex = /^(\s*)(.*)(\s*)$/; 
let result = hello.replace(wsRegex, "$2"); 
console.log(result);

My test results:

let result = hello.replace(wsRegex, "$2"); 
console.log(`"${result}"`);

No, it doesn’t produce the correct output.
Pay attention to the second group. It contains a greedy quantifier. So to fix it you may want to find out how to make it non-greedy.

Thank you!

I noticed afterward that the result was not correct, I just could not see the extra spaces at the end in the console output. Bad testing!
