What’s It All About?

Life is about lists and tables. In programming languages, lists and tables are implemented using arrays.

The JavaScript Array object is a pretty rudimentary implementation of an array (in particular, without work arounds it’s only one-dimensional). But you’ve learned all you need to know to build sophisticated programs with it in this chapter. Better yet, most of the information in this chapter is valid in almost any modern programming language. Naturally, there will be some changes to reflect the specifics of the programming language. But the concepts and techniques you’ve learned in this chapter will provide a solid starting place for programming in any language.

You should also pat yourself on the back! By the time you’ve reached this point, your code, and your programming knowledge, has come a long, long way from the humble beginnings in Chapter 1 of this book! I’m proud of you.

It’s time to move on to the heart of modern programming. In Chapter 7, “ Working with Objects,” you’ll learn what programmers mean by an object and all about how to work with objects.
