Removing Whitespace from Start and End

• Sometimes whitespace characters around strings are not wanted but are there. Typical processing of strings is to remove the whitespace at the start and end of it.

• Let's write a regex and use the appropriate string methods to remove whitespace at the beginning and end of strings.

• Note: The String.prototype.trim() method would work here, but for now you'll need to complete this challenge using regular expressions.

• Ex:
  

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

• result will be equal to the string Hello, World!
