Wasm By Example

Wasm By Example is a community-maintained reference site that teaches WebAssembly through concise, runnable code examples. Each example is presented in multiple source languages — Rust, AssemblyScript, and raw WAT — alongside the corresponding JavaScript integration code and a live demo. Topics range from hello world and basic math to more advanced subjects like reading and writing strings across the boundary, using WebAssembly threads, and implementing simple graphics. It is widely recommended as the most practical starting point for developers new to the WebAssembly API.
