Abstract
Use a dictionary when you want to store items that you need to reference with unique identifier keys. Arrays keep items in the order in which you put the items into the array, while dictionaries don’t guarantee any order at all. However, you can access each item based on the key that you provided when the item was originally added to the dictionary.
