T

he Web is a pretty big deal. It’s a lot of fun to build Web pages, and just 
about every business needs them. As the Web has grown and changed, 

the expectations of what a Web page is and does have also changed. If you 
already know HTML or XHTML, you know how to create Web documents — if 
you need a refresher, check out Bonus Chapter 1 on either the companion 
Web site at www.dummies.com/go/javascriptandajaxfd or my own site 
at www.aharrisbooks.net/jad. 

As the Web has evolved so have the tools that are used to create Web pages 
and documents. JavaScript and AJAX are two powerful tools for creating 
dynamic Web documents. This chapter gets you started with a look at some 
of the primary technologies out there for building Web pages.

Building Something Cool

This book is about adding features to Web pages that you cannot do with 
simple HTML and CSS.

Make no mistake; we’re talking about programming here — and programming 
is a little bit harder than plain old Web development. However, it’s really 
worth it, as the example page in Figure 1-1 illustrates. 

 

To keep this example simple, I’m using some external libraries. They are 
explained in Part IV of this book, but for now just appreciate that something 
exciting is happening here.
