Exercise 07 - Reverse a String

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

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

You will notice in this exercise that there are multiple tests (in the file reverseString.spec.js). Currently, only the first test is enabled. After ensuring that the first test passes, enable the remaining tests one by one by removing the .skip from the test.skip() function.

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.
