The idea was clever: pick a strict, statically-typed subset of JavaScript that an engine could recognize on the fly and compile down to native code. We could get performance similar to NaCl/PNaCl and still have code live inside web content and use web API’s (no separate sandbox, IPC, or alternative API’s). asm.js shipped in Firefox 22 back in 2013 and was a success. It let projects like Unity and Unreal ship C/C++ codebases to the web for the first time, using just standard web technologies. The Epic Citadel demo was ported to the web in just four days. It was a landmark achievement, and a fond memory for the original asm.js team.<br/> <p><strong>Tags:</strong> #asmjs #firefox #javascript #mozilla #wasm</p> Wed, 20 May 2026 16:42:18 +0000 linkding-ssg:bookmark:38549 asmjs firefox javascript mozilla wasm
