Pretty simple, write a function called reverseString that returns it's input, reversed!
reverseString('hello there') // returns 'ereht olleh'You will notice in this exercise that there are multiple tests, after making the first one pass, enable the others one by one by deleting the x in front of the it() function.
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.
