WebAssembly, or wasm, is an efficient low-level programming language for in-browser client-side execution. It is designed to support C/C++ and similar low-level languages. Future versions may be enhanced to better support other languages. WebAssembly is intended to be small, fast to decode, fast to compile, and fast to execute.
