WebAssembly can serve as a companion to JavaScript in web development, taking on performance-intensive tasks.

Most web applications today use JavaScript to run in the browser. JavaScript has been around for ages, and it’s gotten quite fast due to browser optimizations and hardware improvements.

WebAssembly is a binary instruction format and virtual machine that brings near-native performance to web browser applications, and allows developers to build high-speed web apps in the language ...
