Web application programming, the client-side, scripting heavy sort that people are flocking to today, is a path that forces successful application developers to abandon objects. JavaScript is a weak OO langauge, since it lacks inhertience, and polymorphism. There are no namepsaces, so modular programing is difficult. Reuse is already hard enough to coordinate, see how far you get without package/unit/library facilities in the host language. Programmers will buy into the textbook notion that you can work around this with JavaScripts prototypes, but soon find that they have poorly organized, bloated classes. And then, of course, the OO facilities in JavaScript are slow. JavaScript handles many small objects, the natural direction of OO programming, very poorly. I've done some hacking on Mozile, a CSS editor that's built on Gecko. It followed a familiar path in development. In 0.6 they attempted to create an cross-browser abstraction layer, so that the editor would work on IE, Mozilla, and Safari. This never happens, and it didn't happen. The editor only ever worked on Gecko, and because of the extra layer, it worked slowly. In 0.7 the editor is written directly to Gecko. It's functions only, manipulating the DOM. There is a natural direction from this realzation, is toward and application that application uses closures to specify editor behaviors, which, since they are used in all scripted event handlers, are vetted, and perform quite well. -- Alan Gutierrez - alan@e... - http://engrm.com/blogometer/index.html - http://engrm.com/blogometer/rss.2.0.xml
