What Is WebAssembly? An Introduction | HackerNoon
Briefly

WebAssembly (WASM) is a low-level assembly-like language designed for web browsers, enabling cross-platform applications to run efficiently. It serves as a compilation target for various programming languages, allowing developers to harness additional performance capabilities beyond those offered by JavaScript. By translating high-level code into an assembly language structure, developers can create applications that run faster in the browser and perform complex tasks. This article breaks down its workings, illustrating how languages like C are transformed into machine code that can be executed natively in browsers, thereby enhancing web app performance.
WebAssembly is a low-level assembly-like language enabling applications built with different programming languages to run in the browser at near-native speed.
It allows web apps to run faster and manage tasks too heavy for JavaScript, expanding the capabilities of web applications.
