The Worldwide Web Consortium (W3C), the standards body for the Internet, has published three new public working drafts related to WebAssembly: WebAssembly Core Specification, WebAssembly JavaScript Interface, and WebAssembly Web API. WebAssembly is a low-level programming language, similar to assembly, that runs in modern browsers and provides fast performance for Web apps.
The drafts are now available for review, but the W3C made sure to point out that the drafts are not final. The eventual specifications for WebAssembly could be very different than these initial proposals.
