The Book of JavaScript, 2nd Edition

Summary

This chapter has introduced the last two fundamental ideas behind all programming languages: arrays and loops. Now that you've learned about variables, if-then statements, functions, loops, and arrays, you've learned all of the basic aspects of computer programming—so be happy! From now on, everything we learn is specific to how JavaScript works with the browser. All the tough programming nitty-gritty is behind us.

Before you leave this chapter, make sure you've learned how to:

• Create a new array

• Access elements in an array

• Use loops to go through an array's elements

• Use both for and while loops

• Nest loops

• Use associative arrays
