Remove Whitespace from Start and End...Both cases in or

JavaScript
1

Tell us what’s happening:
/^\s+|\s+$/g is supposed to match and replace either ^\s+ or \s+$ …
.
But here, it’s matching and replacing both, Why ?

Your code so far


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


console.log(result);

let some = "aapp"
console.log(some.match(/aa|pp/g));

You have a global flag, that means it finds all matches
