Technical details: The Odin compiler runs in your browser. Even on your phone! This is enabled by an experimental Odin compiler fork called wodin: https://github.com/karl-zylinski/wodin

wodin has a WASM backend that lets it emit WASM directly, without LLVM. The Playground site runs wodin, which compiles the gameplay code and emits new WASM, which is the run within the browser. Note that wodin's WASM backend is AI generated: It's roughly 20000 lines of C++. Nevertheless, I am flabbergasted that this is even possible.
