Getting Started with Rust and WebAssembly: A Practical Guide
Rust + WebAssembly (Wasm) lets you write performance critical web code in Rust, compile it to a portable binary format, and run it in the browser alongside JavaScript. This guide walks you through the full setup, your first project, the core tooling, and where to go next.
1. Prerequisites
Before you begin, make sure you have:
Rust installed via rustup — this is the standard way to manage Rust toolchains.
A terminal (bash, zsh, PowerShell, etc.).
Node.js and npm (optional but useful if you plan to publish packages or use a JS bundler).
Basic familiarity with Rust — you don't need to be an expert, but you should be comfortable with cargo , modules, and functions.
