I mean in an array the elements do not necessarily have to be in an order. For example, var todo = [3,6,10,2,0] I am not sure if I understood this question correctly

An Array will always maintain its order. If your had [3, 4, 6, 8, 3, 2, 2, 45, 1]. This order will remain the same. The value at position [3] will alway be 8 regardless of how many time you call it. Now, a Dictionary (key: value) pairs do NOT maintain the order they are entered. That is why you use the key to access the value, because there is no guarantee that what was second on the first call will be second on the third call.
I hope that helps to clear it up for you. :)
