Regular Expressions - Remove Whitespace from Start and End

JavaScript
1

Hi!! So I actually already passed this challenge a few times (I like to review these) and this time I did this solution and somehow it worked. I really want to know how it worked though; why did it only cut the end spaces and not the one in the middle (producing Hello,World!)? I always check my work with console.log and I actually submitted the work so see if it was right and it did indeed pass the tests. Thank you so much!!

My code:

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

console.log(result)
