I previously didn't have a reason to use arrays, but since someone recently emailed me an example of when you could use arrays , I feel inclined to share it with folks. We have previously covered variables, as a name that holds a value for you.
Arrays are an extension of variables.
Arrays are variables that hold more than one value. You can pick any name for an array name, but from then on, that name can ONLY be used as an array. The really interesting this is that unlike some other languages, you dont have to just use numbers. There are different times you might choose to use arrays. But here are some instances that might be relevant to you.
