"1 tat Knew hew it happened,but ttees an applet in the tagabev and somepnj 'm Tfawag teep& burmr$ my -toast.”
In this part . . .
M^art V begins with a list of some great JavaScript-related Web sites that are full of useful information about all aspects of JavaScript. If you feel the need to communicate with real people about your JavaScript scripts, Chapter 15 even provides you with a list of some user groups that enable you to do just that.
These online resources are followed by a chapter explaining the most common mistakes that people run into when implementing Web pages (along with tips on how to avoid them). And finally, no programming book worth its salt would be complete without at least a few handy debugging techniques. Chapter 17 provides you with lots of bug-related tips that make debugging at least entirely bearable, if not downright pleasant!

^ Taking advantage of the essential JavaScript-related newsgroups
M rnf etting help on how to do something has never been easier than it is right now. Why? The Internet, of course! From its roots in government and university installations, the Internet remained a close-knit, mostly academic community until as recently as a decade ago. Inevitably, commercialism reared its ugly head and has had a tremendous effect — and not all bad, either — on all things Net. (For example, the commercialism of the Internet is directly responsible for the proliferation of Web tools and languages such as JavaScript.)
Although marketing and advertising have become common on the Internet, the spirit of sharing and intellectual collaboration hasn’t yet been snuffed out. Helping other people (and maybe showing off a little in the process) is a fundamental joy. And because access to the Internet is relatively cheap and easy, everybody and their dog indulges — as you see when you visit the URLs and newsgroups that I list in this chapter.
Ten Web Sites to Check Out
With no further ado, then, on to the good stuff: a list of irresistible JavaScript-related Web resources. You find tips, tricks, tutorials, examples, and up-to-the-minute documentation. The site’s URL follows a description of the goodies offered.
256 Part V: The Part of Tens
The Netscape DevEdge site contains a wealth of information on getting started with JavaScript, including a complete language reference, how-to articles, and sample code. It also offers a downloadable JavaScript debugger.
Microsoft maintains an information-packed site devoted to its JavaScript-compatible language, JScript. Documentation, tutorials, sample code, and access to JScript-related newsgroups are just some of the great resources that you find here.
The JavaScript section at CNET features tips and tutorials in addition to copy-and-paste JavaScript code.
Webmonkey maintains a killer JavaScript code library containing not just a wealth of scripts but a handy browser reference chart, cheat sheets on HTML and CSS, and more — all free for the taking.
Project Coot's JavaScript QuickStarts
Project Cool’s JavaScript QuickStarts offer hands-on JavaScript (and DHTML) tutorials. From basic to advanced, all are organized into neat, bite-sized chunks perfect for beginning JavaScript programmers.

Stop, thief!
Most of the sites that I describe in this chapter are commercial sites, and without exception, the JavaScript source code they offer is clearly marked "for free download." (You might have to register your e-mail address before you can download, though, so these companies can stick you on their electronic mailing lists.)
But if you're looking for scripts, you're not limited to commercial sites. You can cut and paste embedded JavaScript source code from any site, with or without that Webmaster's permission, simply by clicking ViewOSource (from Internet
Explorer) or ViewOPage Source (Navigator). (This is one reason why password protection and other highly sensitive features aren't typically implemented in JavaScript!)
One caveat: If you run across source that includes a copyright notice, contact the author or Webmaster and ask for permission before using it. If in doubt, don't copy a file line for line; instead, take a look at how the programmer solved the problem and base your solution on the overall approach.
