Shrinking WebAssembly and JavaScript code sizes in Emscripten – Mozilla Hacks - the Web developer blog
Shrinking WebAssembly and JavaScript code sizes in Emscripten Emscripten is a compiler toolchain for asm.js and WebAssembly which lets you run C and C++ on the web at near-native speed. Emscripten output sizes have decreased a lot recently, especially for smaller programs. For example, here’s a little C code: #include <emscripten.h> EMSCRIPTEN_KEEPALIVE int add(int x, int y) { return x + y; } This

Supercharging JavaScript performance with asm.js
In June we introduced preview support for asm.js, which is now supported by default in Microsoft Edge starting with Microsoft EdgeHTML 13. With this change, Hosted Web Applications and the WebView in any Universal Windows Application can now benefit from asm-optimized code as well. Asm.js is a strict subset of JavaScript that can be used as a low-level and efficient compile target. It applies cons
GitHub - WebAssembly/binaryen: Optimizer and compiler/toolchain library for WebAssembly
Binaryen is a compiler and toolchain infrastructure library for WebAssembly, written in C++. It aims to make compiling to WebAssembly easy, fast, and effective: Easy: Binaryen has a simple C API in a single header, and can also be used from JavaScript. It accepts input in WebAssembly-like form but also accepts a general control flow graph for compilers that prefer that. Fast: Binaryen's internal I

Writing code for multiple platforms can be a lot of work. It can be even more work to have to completely rewrite it for each one, too. What if you wrote an application in C++, but wanted it to be displayed in the browser somehow? Well n

Since our first benchmarks using early Spartan builds some time has passed. This is how Edge performs WebGL on the final version of Windows 10. Earlier builds of Windows 10 indicated already that Edge (Spartan) might declass

A couple of months back, we announced that we had started development on Asm.js. Support for Asm.js has been one of the top 10 most-requested items at the Microsoft Edge Developer Suggestion Box on UserVoice since we launched it in December 2014. Since that time, we’ve made good progress, and in Windows 10 Insider Preview builds starting with 10074, we are now previewing the early work that we’ve
