The WebAssembly Specification

The WebAssembly Specification defines a standardized format for a low-level programming language that runs efficiently in web browsers and other environments. It ensures programs written in WebAssembly are portable, secure, and perform close to native speed. WebAssembly allows developers to compile code from languages like C++, Rust, or others into a compact, binary format, enabling fast execution and broad compatibility across platforms. The specification details how WebAssembly modules are structured, how they interact with the environment, and how they execute, providing a foundation for high-performance web applications and beyond.
