Chapter 26. Introduction to JavaScript

by Aaron Gustafson

A web page that is semantically marked up and beautifully designed (with CSS, of course) is wonderful, but to really make it an experience, it needs some interactivity. This is what we call the "behavior layer" and, in most cases, it is made possible through use of a technology called JavaScript . This chapter will walk you through a little history of the JavaScript language and then discuss the basic building blocks of modern JavaScript.
