Exercise 03 - Reverse a String

Pretty simple, write a function called reverseString that returns its input, reversed!

reverseString('hello there') // returns 'ereht olleh'

Hints

Strings in JavaScript cannot be reversed directly so you're going to have to split it into something else first.. do the reversal and then join it back together into a string.
