#42For information rich applications (ie. B2B-ish), definitely ExtJS. Pretty steep learning curve since, unlike jQuery UI, you sorta have to take all of nothing. We use ExtJS everywhere where using data/information is more important than look-n-feel. Put together CoffeeScript (http://jashkenas.github.com/coffee-script/) with ExtJS and you'll be in RIA dev heaven. Fast and very productive.
For applications where look-n-feel, customization, etc is more important (ie. B2C-ish or consumer internet), HTML/CSS/jQuery is the way to go.

#43Earlier quoted context omitted.
are you absolutely sure? here's an excerpt from their website: """ Cappuccino was implemented using a new programming language called Objective-J, which is modelled after Objective-C and built entirely on top of JavaScript. Programs written in Objective-J are interpreted in the client, so no compilation or plugins are required. Objective-J is released alongside Cappuccino in this project and under the LGPL. """ http:…
I'm developing an objective-j app right now and they have compile targets that compile directly to minified javascript. It will work without compiling but for a production I wouldn't recommend it for bandwidth reasons alone. Technically they are right the javascript is still interpreted in the client and you don't need any browser plugins to run it. It's not strictly objective-j source code your are running in a prod…
Actually, the main difference between debug and release are that release builds also minify/compress the code. Both compile from objj to js.
Of course, you can not run the compiler at all and the code will still run in your browser, because it will do the compilation "just in time". There's not a significant performance penalty for doing this, and browser refreshes are still speedy. But when you're ready to deploy, you might as well build ahead of time even for a 10-20% launch time speedup.
