A good example would be my Identity Mod. The arrays function exactly the same as normal variables, but it is merely more efficient to use them rather than a slew of different variables when you have a large amount of things to define.

In the code above I use arrays over 500 times, and I do this because it would be a giant loving pain in the ass to come up with a different name for each variable.
tl;dr: Arrays are used primarily to handle large variable groups.
