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. The Wasm stack machine is designed to be encoded in a size- and load-time-efficient binary format. WebAssembly aims to execute at native speed by taking advantage of common hardware capabilities available on a wide range of platforms. WebAssembly describes a memory-safe, sandboxed execution environment that may even be implemented inside existing JavaScript virtual machines. When embedded in the web, WebAssembly will enforce the same-origin and permissions security policies of the browser. WebAssembly is designed to be pretty-printed in a textual format for debugging, testing, experimenting, optimizing, learning, teaching, and writing programs by hand. The textual format will be used when viewing the source of Wasm modules on the web.

A TypeScript-like language for WebAssembly. AssemblyScript targets WebAssembly's feature set specifically, giving developers low-level control over their code. Its similarity with TypeScript makes it easy to compile to WebAssembly without learning a new language. Integrates with the existing Web ecosystem - no heavy toolchains to set up. Simply npm install it! AssemblyScript is free and open source software released under the Apache License, Version 2.0, builds upon Binaryen and is based on the WebAssembly specification.
