What is NodeJS?

🚀 NodeJS Essentials

NodeJS is a Runtime Environment for JavaScript, created by Ryan Dahl by embedding Chrome's V8 Engine with C++.

🔧 Key Capabilities:

1. Run JS code outside browsers
2. Native machine access via C++ (file handling, system tasks)
3. Create web servers using JavaScript

💡 Core Idea: JavaScript everywhere (client & server) through V8 + C++ combo
