How-To Howto Webassembly
I’ve started seeing WebAssemly (WASM) stuff popping up in a few places, most notably CloudFlare’s recent anti-container isolated v8 workload stuff and I wanted to understand it a little better. Essentially, WebAssembly is a way to compile stuff to a browser-native binary format .wasm, which you can then load with JavaScript and interact with. Simplest C Since this is binary, I wanted to start with a C program. Since it’s C, to avoid includes or C<->JS string handling, I’m just going to return 42 like other tutorials start with :)
