Using WebAssembly in your ReactJS App

What is WebAssembly?

WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable target for compilation of high-level languages like C/C++/Rust, enabling deployment on the web for client and server applications.

Alongside HTML, CSS and Javascript, it is the fourth language to run natively in browsers and supports the 4 major browser engines – Firefox, Chrome, Safari and Edge.

WebAssembly allows you to run code at native speed that is able to work with the JavaScript context and access browser functionality through the same Web APIs accessible from JavaScript. It basically allows you to run your code in native speed inside a browser.
