To access an element in an array you can do something like this:

let value = array[index]

If you want to get the fifth element of an array, you use an index of 4, like this:

let fifthElement = array[4]

This is because the index of an array starts at 0. So the first element has an index of 0, and therefore the fifth element has an index of 4.
