WebAssembly (WASM)

A binary instruction format that enables near-native execution speeds for high-performance applications in web browsers and beyond.

WebAssembly (Wasm) provides a portable compilation target for languages like C++, Rust, and Go: allowing them to run alongside JavaScript with predictable performance. It operates as a stack-based virtual machine within a memory-safe, sandboxed environment to ensure security without sacrificing speed. Major industry players including Google, Mozilla, and Microsoft support the standard: enabling complex tools like AutoCAD and Adobe Photoshop to migrate to the web. Beyond the browser, the WebAssembly System Interface (WASI) extends these capabilities to server-side environments and edge computing: offering a lightweight alternative to traditional containers.
