Google, Apple, Microsoft and Mozilla are teaming up to create WebAssembly, a bytecode that will make web browsers up to 20 times faster performance.
Bytecode is a machine-readable instruction set which browsers can load quicker than high-level languages. It is also more efficient for both desktop and mobile browsers.
WebAssembly will include both a binary notation, that compilers will produce, as well as a corresponding text notation, which will be used in debuggers or development environments.
