Node.js Explained - How JavaScript Runs on Servers | Full Stack Development #34
JavaScript used to live only in the browser. Node.js changed that — it put JavaScript on the server, so you can build your entire stack in one language. In this video we break down exactly what Node.js is and use it to scaffold TaskFlow's backend from scratch.
You'll learn:
What Node.js actually is — the V8 engine + libuv
The event loop, and why Node is single-threaded but non-blocking
Core modules: fs, path, and the process object
Environment variables with process.env and dotenv (keep secrets out of your code)
The REPL, nvm for version management, and package.json in depth
Scaffolding TaskFlow's backend: package.json, scripts, and clean environment config
