A 192-Byte WebAssembly Compiler: Code Golfing Extravaganza
2025-01-24

This article details a WebAssembly compiler, a mere 192 bytes in size, capable of compiling reverse Polish notation expressions into WebAssembly modules. The author systematically deconstructs the code's optimizations, revealing clever uses of JavaScript features, WebAssembly bytecode manipulation, and variable/expression streamlining. While functionally simple, this tiny compiler offers a deep dive into the inner workings of WebAssembly.
