[MX2004PRO] What is the point of an array

Ok, maybe this is dumb but I seriously don’t know. I have been using FLASH for years and I make websites with it as my regular job but I have never had to deal with arrays so never learned them. I really want to, I saw Kirupa’s tutorial but I still don’t understand what they are for. Could someone give me some examples as to their usage? Why do I need an array? What can I do with them? I am usually creative with my FLASH techniques and I know arrays are useful but I am like a monkey with a revolver…I know they have power, but what are they for?

Any help would be appreciated,
