Saying Goodbye to Asm.js

Farewell to Asm.js: The WebAssembly Era Arrives 🌐



The Asm.js compilation target is being discontinued, marking a significant shift towards WebAssembly (WASM) as the preferred technology for running high-performance code in web browsers, offering enhanced security, efficiency, and compatibility. This transition streamlines web development by allowing developers to compile languages like C, C++, and Rust directly into WASM, which can then be executed within web environments.
