The first public working drafts of WebAssembly 2.0 have arrived, with the planned next iteration of the binary instruction format so far centering on capabilities such as JavaScript interaction and integration with the broader web platform.
The WebAssembly Working Group of the World Wide Web Consortium (W3C) on April 19 published three drafts:
- WebAssembly Core Specification Version 2.0, describing the next version of the core standard.
- WebAssembly JavaScript Interface Version 2.0, providing an explicit JavaScript API for interacting with WebAssembly.
- WebAssembly Web API Verson 2.0, describing the integration of WebAssembly with the broader web platform.
The three drafts follow the same pattern as for WebAssembly 1.0, with the W3C in late-2019 publishing documents pertaining to the core specification, a web API, and a JavaScript interface. The core specification of WebAssembly 2.0 echoes previous goals for WebAssembly. Design goals include fast, safe, and portable semantics and efficient and portable representation.
