Nodejs

What is Node.js?

Node.js is the runtime environment that lets us run JavaScript outside of the browser.

Node.js is asynchronous and event driven, which is good for scalable network applications.

Simple Node.js web server:

const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});
