Summary

Chapter eight introduces arrays. Arrays allow you to store multiple values in a single variable. Arrays consist of zero or more elements. Each element is a value. An array is the collection of values. In this chapter you learn how to create arrays, modify them, and iterate through an array’s elements.

Supplementary Material

Both Udacity and LearningLad have videos explaining the concepts presented in this chapter. The videos by Udacity covers both looping and arrays and is more instructional in nature. The videos by LearningLad cover arrays only and are more tutorial in nature. You should watch both sets of videos.

Udacity

Refer to this playlist for videos on Looping and Arrays. The playlist here covers both looping and arrays. It is a good supplement to this chapter and the previous chapter.
