🔹 What is Node.js?

Node.js is not a new language, it’s a runtime environment that allows JavaScript to run on the server 🖥️.

It enables developers to use JavaScript for both front-end and back-end development 🚀.

✨ Key features:

1. Built on the fast V8 engine ⚡
2. Perfect for real-time applications like chats 💬
3. Supports asynchronous programming ⏳
4. Huge package ecosystem (NPM) 📦
5. Easy to learn if you already know JavaScript ✅

➡️ In short: Node.js = the bridge that brought JavaScript from the browser to the server. 🟩
