+# Exercise 02 - Reverse a String.
+
+Pretty simple, write a function called `reverseString` that returns it's input, reversed!
+
+```javascript
+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.
