TRANSCRIPT
So far, all of the variables that we have seen can only hold one (or zero) values. However, we sometimes need to be able to store multiple values so that we can carry them around in a single variable rather than porting multiple variables around. To do this, we can use an array. This is essentially a list of values. Arrays also have a lot of functionality attached to them to help retrieve or modify certain values or attributes. We won’t explore all of the functions, but we can go over some of the more commonly used ones. First, to create an array, we create a variable but store multiple values within []. We can store values all of the same type or of a single type.
