From InfoWorld: Mozilla has taken concrete, if small, steps to realizing WebAssembly, a next-generation approach to Web browsers supporting scripting in multiple languages.
Based on a recent blog post, Mozilla has produced a working toolchain to compile code into WebAssembly. The toolchain is still a long way from from being casually usable, though. Right now, it consists of multiple pieces back-ended together rather than unified, end-to-end tools.
What's more, all of the work taking place right now won't have any measurable meaning for the user until WebAssembly support actually arrives in the browser.
The current toolchain more or less picks up where asm.js left off. Existing projects that compile to C/C++ can be converted to WebAssembly, as can projects already converted to asm.js. But a true one-step conversion process -- C/C++ to WebAssembly, or support for most any other language apart from JavaScript -- is a ways off.
