How would I retrieve an item through subscript syntax?
// Enter your code below
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(7)
[1,2,3,4,5,6] + [7]
let value = arrayOfInts

arrayOfInts[0] // This retrieves the first item from the array.
It's important to note that array indexes are 0 based, meaning that they start at 0. The first item would therefore be [0], the second item [1] and so on.

2,108 Pointsfor some reason I am inputing let value = arrayOfInts[5]
but it is not accepting my answer.

28,558 PointsThat would be because of array indexes being 0 based. As I mentioned in my post [0] is the first item, [1] is the second item and so on. This means that [5] actually refers to the sixth item in the array.
To retrieve the fifth item which is what the task asks you have to use [4]. 0-based lists are often confusing to people new to programming at first, but they are so common in programming that you will get used to them eventually.
