🌱 Node.js Tutorial: Building Your First Application

Node.js is a powerful runtime environment that allows developers to run JavaScript on the server side. Whether you're a beginner or an experienced developer, this guide will help you get started with Node.js.

📦 Getting Started

Install Node.js
Download the latest version from Node.js official website and follow the installation instructions.
Initialize a Project
Open your terminal and run:
```
npm init -y
```
Create a Simple Script
Add a hello.js file with the following code:
```
console.log("Hello, Node.js!");
```
Run it using:
```
node hello.js
```

📚 Core Features

Event-Driven Architecture
Node.js uses an event loop to handle asynchronous operations efficiently.
Non-blocking I/O
Node.js excels at handling multiple requests simultaneously without blocking.
Module System
Use npm modules to extend functionality. For example:
```
npm install express
```

🧱 Practical Examples

Build a Web Server

const http = require('http');
http.createServer((req, res) => {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(3000);

Use Express Framework

Start with: ```bash npm init -y npm install express ```

Then create a basic app:

const express = require('express');
const app = express();
app.get('/', (req, res) => res.send('Welcome to Node.js!'));
app.listen(3000);
