WebAssembly (Wasm)
Also known as: WebAssembly / Wasm / ウェブアセンブリ
A binary instruction format that runs near-native speed in browsers. Code written in C, C++, Rust, or Go can compile to Wasm. The WASI extension enables portable server-side and edge execution.
Overview
WebAssembly was designed to run numerical computation, image processing, and audio in browsers at near-native speed. Edge runtimes like Cloudflare Workers and Fastly also execute Wasm containers.
Mobile Trends
Post-2026 mobile frameworks are increasingly exploring Wasm for server-driven UI delivery. See mobile framework future trends for the broader picture.
