Jan 31, 2025 · WebAssembly is a type of code that can be run in modern web browsers — it is a low-level assembly-like language with a compact binary format that runs with near-native performance and provides languages such as C/C++, C# and Rust with a compilation target so that they can run on the web.

WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications. Developer reference documentation for Wasm can be found on MDN's WebAssembly pages.

WebAssembly (Wasm) defines a portable binary-code format and a corresponding text format for executable programs [2] as well as software interfaces for facilitating communication between such programs and their host environment. [3][4][5][6]

Jan 31, 2025 · To use WebAssembly in JavaScript, you first need to pull your module into memory before compilation/instantiation. This article provides a reference for the different mechanisms that can be used to fetch WebAssembly bytecode, as well as how to compile/instantiate then run it. What are the options?

WebAssembly (Wasm) is an universal low level bytecode that runs on the web. It is a compilation target for languages like Rust, AssemblyScript (Typescript-like), Emscripten (C/C++), and much more! Wasm offer a compact binary format with predictable performance, and portability to run alongside Javascript and other host languages.
