WebAssembly Specification

WebAssembly is a low-level, efficient code format designed for fast execution in web browsers. It allows developers to run complex applications—like games or software—directly in the browser without relying on traditional methods like JavaScript. The WebAssembly Specification defines how this code is created, validated, and executed consistently across different platforms. It acts as a blueprint ensuring WebAssembly programs are secure, reliable, and performant, enabling developers to harness near-native speed for web applications while maintaining cross-browser compatibility.
