Adobe has just announced a huge donation to the Mozilla foundation: a high performance ECMAScript Edition 4 Virtual Machine. Don’t know what ECMAScript is? It’s the standard behind JavaScript. Off course this is great news for all Ajax developers because it allows us to rely on the most powerfull Virtual Machine ever for our applications.

When you convert PDF to Word you may find that any free PDF conversion sites online don’t give you the power that true PDF to Word software can give you; if you end up converting PDF to Word often then dedicated software might be a good solution.

Mozilla will host a new open source project, called Tamarin, to accelerate the development of this standards-based approach for creating rich and engaging Web applications. The Tamarin project will implement the final version of the ECMAScript Edition 4 standard language, which Mozilla will use within the next generation of SpiderMonkey, the core JavaScript engine embedded in Firefox®, Mozilla’s free Web browser. As of today, developers working on SpiderMonkey will have access to the Tamarin code in the Mozilla CVS repository via the project page located at www.mozilla.org/projects/tamarin/ . Contributions to the code will be managed by a governing body of developers from both Adobe and Mozilla. “Adobe’s work on the new virtual machine is the largest contribution to the Mozilla Foundation since its inception,” said Brendan Eich, chief technology officer, Mozilla Corporation, and creator of JavaScript. “Now web developers have a high-performance, open source virtual machine for building and deploying interactive applications across both Adobe Flash Player and the Firefox web browser. We’re excited about joining the Adobe and Mozilla communities to advance ECMAScript.” “This is a major milestone in bringing together the broader HTML and Flash development communities around a common language, and empowering the creation of even more innovative applications in the Web 2.0 world,” said Kevin Lynch, senior vice president and chief software architect at Adobe. “By working with the open source community we are accelerating the adoption of a standard language for creating and delivering richer, more interactive experiences that work consistently across PCs and mobile devices.”

Hopefully this will have an influence on the other browsers too and push them towards powerfull and standard compliant JavaScript implementation. I just can’t wait to see it in action
