Trim function lab

In this lab, you will implement a trim function that will remove leading and trailing whitespace from a given string. This function should mimic the behavior of the built-in String.prototype.trim() method.

Your trim function should accept a single string argument and return a new string with leading and trailing whitespace removed.

Example:

trim('  Hello World  ') // should return 'Hello World'

Do not use the built-in String.prototype.trim() method in your implementation.
