The challenge asks for the 5th item in the array. Remember that the array is indexed starting from 0. So the first item in the array is at index 0. Second item is at index 1. Third item is at index 2 and so on.

So if you want 5th item in the array, it will be at index 4.

let value = arrayOfInts[4]
