JavaScript: Novice to Ninja

Chapter 3Arrays, Logic, and Loops

In the last chapter we were introduced to JavaScript’s primitive values, and also did a bit of programming. In this chapter we’re going to look at arrays, a useful data structure for storing lists of values. We’ll also look at logical statements that allow us to control the flow of a program, as well as loops that allow us to repeat blocks of code over and over again.
