The whole text format is under construction, so I'll use theĬurrent temporary S-Expression syntax in this presentation: (This means we can use asm.js to write polyfills!)īut there is a lot more we want to do next! The initial release focuses on a Minimum Viable Product: compiling C/C++, better asm.js. WebAssembly is being specified and shipped iteratively. Want to ship this year (with usual standardization caveats) More iteration before stable spec and ship in browsers Recently reached Firefox/Chrome/Edge interop milestone!
