Next-Gen JavaScript Interpreter Speeds Up WebKit

JavaScript is everywhere these days. Now WebKit, the framework behind (among others) Safari and Safari Mobile, as well as the yet-unreleased Android, is getting a new JavaScript engine called Squirrelfish, which the developers claim provides massive speedups over the previous one. The current iteration of the engine is "just the beginning," they claim; in the near future, six planned optimizations should bring even greater speed. With JavaScript surviving as a Web-page mainstay despite many early gripes, and now integral to some low-powered mobile devices, this may mean many fewer wasted seconds in the world.

According to this link, the SquirrelFish in the latest nightly build (without the extra optimizations) can already compile *and* run the source code between 1.08x and 1.94x as fast as Tamarin when Tamarin is just running pre-compiled code. It's fast.

Javascript grows up

"With JavaScript surviving as a Web-page mainstay despite many early gripes..." This notion has long been outmoded... well, at least for the past few years.

Javascript is doing more than just surviving. Early implementations of Javascript were quite buggy and standards were pretty lax. Things have improved significantly since "Javascript" became ECMAScript. The name may still have "script" in it, but it's a huge misnomer. Javascript is a full-fledged language - a very powerful one with many unique properties, and very useful if you know how to apply design patterns.

I encourage anyone involved in building websites, widgets, or enterprise applications to check out the Javascript lecture series by Douglas Crockford of Yahoo! located at http://video.yahoo.com/video/play?vid=111585 to get a real feel for the power of modern Javascript.

And have a look at the modern AJAX frameworks like YUI and JQuery, which are being used to develop some pretty complex applications.
