WebAssembly is a binary instruction format designed to run code on the web at near-native speed. It allows developers to write code in languages like C, C++, and Rust, which can then be compiled into a format that web browsers can execute efficiently. This makes it possible to run complex applications, such as games and graphics-intensive software, directly in the browser without needing plugins. One of the key benefits of WebAssembly is its portability. Code compiled to WebAssembly can run on any platform that supports it, including desktops, tablets, and smartphones. This enables a consistent experience across different devices and operating systems, making it easier for developers to reach a wider audience.
