Summary from the TLDR Web Dev newsletter

This is an article about creating a minimal JavaScript compiler that converts reverse Polish notation expressions into WebAssembly bytecode. It starts with an extremely compressed 192-byte version and gradually de-obfuscates the code, explaining various JavaScript tricks used for brevity. Through this process, insights into WebAssembly structure, JavaScript optimizations, and compiler design are provided.
