WebAssembly in the browser

WebAssembly was originally invented as a technology solution to speed up code execution inside web browsers. It does not provide a full replacement for JavaScript, but rather works side-by-side with JavaScript. The idea is that JavaScript functions could pass computationally intensive tasks to WebAssembly functions. In this tutorial, we will demonstrate how a simple WebAssembly in-browser application works. The source code of the tutorial is here. A WebAssembly application typically has two parts.…

Rust and WebAssembly

In this tutorial, we will create a very simple but complete WebAssembly application. A WebAssembly application typically has two parts. The bytecode program that runs inside the WebAssembly virtual machine to perform computing tasks The host application that provides UI, networking, database, and calls the WebAssembly program to perform key computing tasks or business logic In this tutorial, the host application is written in JavaScript and runs inside a web browser.…

A Rusty hello world

While WebAssembly supports many programming languages, Rust by far has the best tooling. Rust is voted the most beloved programming language by StackOverflow users for the past 4 years in a row. It is one of the fastest-growing programming languages. Rust is versatile and performant like C, but much safer than C due to its compiler design. Like C, it has a bit of a learning curve. In this tutorial, I will get you started with the Rust programming language.…
