The number of new features added to JavaScript in the past year is substantial. Between Canvas, WebGL, WebSockets, WebWorkers, Audio Data, TouchEvents, the number of permutations of new kinds of browser-based apps you can build will keep anyone busy for years. Then add NodeJS, and CouchDB, and the use of JSON as a data interchange and there are things you can do entirely in JavaScript that no other language can do.

If JavaScript continues to be improved (Harmony, V8/Spidermonkey engines, etc) then I see no other language on the horizon that will replace it.



Everything you listed actually has nothing to do with Javascript as a language. These are new frameworks for the and clientside APIs, not language features.


That's like saying the addition of the DOM did not improve Javascript. Standardized API's do matter, and do improve programming languages.
