Summary

My head hurts! Not from too much technical information, but from being so excited. Arrays are such an eloquent way to store and manipulate data, it’s a shame that some people go through life without ever once experiencing their benefits. Seriously, arrays are awesome.

You saw how arrays could be structured to hold lots of discrete data in whatever way you want. Actually, the stage at which you design how to structure your arrays is the most challenging. As far as what you populate your array with, you learned it could be of any data type, including arrays. In this way, you could have an array full of nested arrays. After you populate an array with data, it is a snap to access and see or change any particular item. Looping through an array is a breeze, too.
