To many people, the word “JavaScript” conjures up memories of annoying popups, irritating mouse-trails, and frustrating no-right-click scripts. If you’ve ever beenon the receiving end of such a script, you’ll know how tedious they can be. Yet JavaScript is a mature, professional scripting language that’s used on the majority of modern web sites, and is a key component in almost all web-based applications. Hang on! Are we talking about the same technology here?


As with so many histories, both perceptions are reasonably accurate: JavaScript does have a dubious reputation, which it earned mainly in the first dot com boom when it was used for little else than opening popups, shielding code from casual scrutiny, and adding pointless whizz-bang effects. And in recent years, as both the web development community and the world at large have become more aware of accessibility issues, JavaScript has been singled out as a cause of many problems, though in reality, it’s not the technology itself that’s at fault—it’s the poorly planned and careless use that has given JavaScript this reputation.

Yet with the increasing popularity of remote scripting techniques (popularly referred to as “AJAX”), JavaScript is enjoying something of a renaissance. Designers, developers, and programmers from many different disciplines are becoming interested in—and impressed by—what was once the domain of specialists. Browser
vendors and other technology companies are taking another look at the potential of this powerful language, as the line between the Web and the desktop becomes increasingly blurred.
