WebAssembly

WebAssembly (sometimes abbreviated Wasm) is an open standard that defines a portable binary-code format for executable programs, and a corresponding textual assembly language, as well as interfaces for facilitating interactions between such programs and their host environment.[2][3][4][5] The main goal of WebAssembly is to enable high-performance applications on web pages, but the format is designed to be executed and integrated in other environments as well, including standalone ones. WebAssembly (i.e. WebAssembly Core Specification (then version 1.0, 1.1 is in draft[9]) and WebAssembly JavaScript Interface[10]) became a World Wide Web Consortium recommendation on 5 December 2019,[11] alongside HTML, CSS, and JavaScript... In November 2017, Mozilla declared support "in all major web browsers",[39] after WebAssembly was enabled by default in Edge 16.[40] The support includes mobile web browsers for iOS and Android. As of July 2021, 94% of installed browsers support WebAssembly... WebAssembly is supported on desktops, and mobile, but on the latter, in practice (for non-small memory allocations, such as with Unity game engine) there are "grave limitations that make many applications infeasible to be reliably deployed on mobile browsers https://en.wikipedia.org/wiki/WebAssembly

Its initial aim is to support compilation from C and C++,[47] though support for other source languages such as Rust, .NET languages[48][49][44] and AssemblyScript[50] (TypeScript-like) is also emerging. After the MVP release, there are plans to support multithreading and garbage collection[51][52] which would make WebAssembly a compilation target for garbage-collected programming languages like C# (supported via Blazor), F# (supported via Bolero[53] with help of Blazor), Python, and even JavaScript where the browser's just-in-time compilation speed is considered too slow. A number of other languages have some support including Python,[54] Java,[55] Julia,[56][57][58] Zig,[59] and Ruby,[60] as well as GoLang.[61]
