What is WebAssembly (WASM)?

WebAssembly (WASM) is an industry-standard programming language for running binary programs in web browsers with near-native performance. WASM's main goal is to enable high performance web applications, and is designed to be a compilation target for any language, including JavaScript, which has long been the primary programming language for web browsers. Since WASM is the product of an ongoing collaboration between the Web 3 Consortium (W3C), Google, Apple, Mozilla, and Microsoft, this standard has built-in support in all major browsers for all platforms and does not need additional plugins to operate within most environments.
