I wrote this guide because I’ve spent a lot of time trying to understand the WebAssembly specification for my own projects. it’ll make other people’s attempts a little easier. WebAssembly is a low level that can be run in various contexts such as a web , a server side , and so on. It’s intended to be a fast, sandboxed target. While it is low level, it’s not quite as low level as regular assembly.
