This is excellent. With all of these upcoming browser enhancements, W3C-standard web applications will look and perform like Windows 3.1 apps or maybe even better.

i hate javascript. i block it with noscript and it gets annoying when i have to allow the websites for noscript.

I hated JavaScript until I saw some of John Resig's work. Now I love it. (This is *not* an exaggeration.)

I didn't want to get into jQuery, but then I did a few things with ExtJS that I wanted to replicate in WP and it was worth the effort!

My friend, you lead a sheltered life.

@SparkyFlary why block it? you're missing out on sooo many features, soon browsers will be useless without Javascript I assure you

[billybaloop]

Well, there really is no reason to vote this down. Its a preference.

@eryksun is it really lossy? I mean, surely it only stores the difference from frame to frame, so it's effectively a 0b cost for static images.

A great overview of new developments in web browser technology. JavaScript implementations are getting much faster and browsers are providing native support for common web application development patterns.

It sounds like the role of JavaScript libraries like jQuery and Dojo will be larger in the future. They provide a convenient, high-level abstraction which can easily optimize itself based on the capabilities of the browser.
