Google, Apple, Microsoft and Mozilla are partnering to create new WebAssembly, a bytecode for use in the new browsers of the future that promises up to 20 times faster performance.

WebAssembly is a project to create a new bytecode (a machine-readable instruction set that’s quicker for browsers to load than high-level languages) that’s more efficient for both desktop and mobile browsers to parse than the full source code of a Web page or app.

Browsers currently use JavaScript to interpret code and enable functionality on websites such as forms and dynamic content. Improvements have been made to load times via asm.js, but bytecode-based systems like .NET are faster.
