A Pythonista's Introductory Guide to Web Assembly
summary
Explains concrete results and tools: piodide runs CPython compiled to Wasm in the browser, uses emscripten/LLVM and runtimes like wasm3 and wasmer for Python, and reports a numeric benchmark where Wasm runs about 40× faster than Python (native C about 80× faster than Python in the example). Shows hand‑writing .wat, assembling to .wasm, and building a tiny compiler that emits .wat/.wasm with imports for I/O and a working demo.
