Summary

In this chapter, you learned quite a bit about the basics of JavaScript, beginning with how to add scripting elements to your pages, how to hide them from incompatible browsers, and how to create comments within the script. You then saw a brief “Hello World” example, which showed you a working JavaScript.

From there, you were introduced to functions, how they’re declared, and how they’re called from the body of the script. Then you learned about variables, how they’re created, how values are assigned to them, and some special ways in which they can be incremented and decremented. In that same section, you were introduced to arrays.
