Introduction to WebAssembly

wasmwebassemblyperformance

WebAssembly (Wasm) is a binary instruction format that runs in modern browsers at near-native speed.

Why Wasm

JavaScript is fast, but compiled languages like C, Rust, and Go can be faster for compute-heavy tasks. Wasm lets you run that code in the browser safely.

Use Cases

  • Image and video processing
  • Game engines
  • Scientific simulations
  • Language runtimes (Python, Ruby) in the browser

Wasm complements JavaScript. It does not replace it.
