Google, Microsoft, Mozilla And Others Team Up To Launch WebAssembly, A New Binary Format For The Web

The team notes that the idea here is not to replace JavaScript, by the way, but to allow many more languages to be compiled for the Web. Indeed, chances are that both JavaScript and WebAssembly will be used side-by-side and some parts of the application may use WebAssembly modules (animation, visualization, compression, etc.), while the user interface will still be mostly written in JavaScript, for example.

This is huge news.
