JavaScript: Novice to Ninja, 2nd Edition

Chapter 3: Arrays, Logic, and Loops

In this chapter we’ll look at some of the data structures used in JavaScript to store lists of values. These are called arrays, sets, and maps. 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.

This chapter will cover the following topics:
