Javascript all the way

These days I’m playing with NodeJS. And today I was thinking about the fundamental change in Javascript. A few years ago it was a darn language for the web. Now someone could query a database using Javascript (CouchDB), create the server portion of a web application using Javascipt(NodeJS), create the browser portion of a web application using pure and fast Javascript, and even create a pure mobile interface using Javascipt (Appcelerator Titanium). Google has proposed a language trying to replace Javascript called Google Dart, but I seriously doubt Google will succeed.
