# WebAssembly

Unclassified · [Official website](https://webassembly.org/)

WebAssembly, often shortened to Wasm, is an open web standard developed at the W3C that defines a compact binary format browsers can run at near-native speed. Code written in languages such as C, C++ or Rust is compiled to it and runs alongside JavaScript. It is a technology, not a service, so it does not set cookies or contact a third party on its own.
