How do you create a simple HTTP server in Node.js?

You can create a simple HTTP server using the built-in http module. Here’s an example:

const http = require('http');
const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello, World!\n');
});
server.listen(3000, () => {
  console.log('Server running at http://localhost:3000/');
});

This code sets up a server that listens on port 3000 and responds with “Hello, World!” to any request.
