Drop-in JavaScript Performance
New video:
upgrading – providing new features from the latest specifications. We’ll look at modern JavaScript and DOM techniques that you can easily drop in to your applications for instant speed-ups. Speaker: John Resig John Resig is a JavaScript Evangelist for the Mozilla Corporation and the author of the book Pro JavaScript Techniques. He’s also the creator and lead developer of the jQuery JavaScript library. Currently, John is located in Boston, MA. He’s hard at work on his second book, Secrets …
@SparkyFlary why block it? you’re missing out on sooo many features, soon browsers will be useless without Javascript I assure you
My friend, you lead a sheltered life.
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!
john resig, without watching im giving 5 stars : D
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 hated JavaScript until I saw some of John Resig’s work. Now I love it. (This is *not* an exaggeration.)
i hate javascript. i block it with noscript and it gets annoying when i have to allow the websites for noscript.
I was surprised the speaker made no mention of Gears, which is at the forefront of changes coming to HTML 5 (though they’re not the same). Also, it may not be clear in this presentation, but Workers (Gears’ WorkerPools) are real threads (or processes) that can execute in parallel on a SMP system. It’s not a simulated thread based on timers. They are limited to message passing, however, which while simpler and safer than shared memory, is not as efficient.
Google: While this format is an improvement, i.e. showing the presentation next to the video, the presentation is still getting encoded like video, which is extremely lossy for static images. I’d like to see a presentation layer, in addition to captioning and annotations, that boxes the video (PIP) while displaying a synchronized sreencast.
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.
