Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. It uses an event-driven, non-blocking I/O model.
const http = require('http');
const server = http.createServer((req, res) => {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('Hello World!\n');
});
server.listen(3000, () => {
console.log('Server running at http://localhost:3000/');
});Node.js brings JavaScript to the server, enabling full-stack development with a single language.
