Mark Perkins, a Senior Web Developer at VGroup has summarized in this blog post the ubuiquity of JavaScript on the Web and how this dynamic language is empowering all kinds of new possibilities in applications. From ECMAScript to ActionScript, Flash to W3C, Google and Yahoo Maps, Apple's Mobile Me, Aptana Jaxer, Rhino, Firefox, Apple Gadgets, Google Gadgets, Yahoo Gadgets, and even Vista Gadgets, and Adobe AIR, (and more), Mark highlights how JavaScript is at the core of the future of the Web not just online, but on the desktop and on mobile devices as well.

Only thing I'd add to Mark's comments is that JavaScript is set to get even faster than the already blazing improvements delivered by Mozilla Firefox and the Webkit engine that powers iPhones and Sarafi. Projects like Tamarin and its convergence with Mozilla's SpiderMonkey (which Aptana Jaxer, the open source Ajax server uses) are slated to provide the equivalent of Just-In-Time (JIT) compliation of JavaScript and open even greater possibilities for greater JavaScript use.
