What attracts you to using Node.js instead of Java for development?

Node.js attracts with its asynchronous, event-driven architecture, which allows efficient handling of a large number of concurrent connections without blocking. This is especially convenient for developing network applications and APIs. Unlike Java, which often uses multithreading, Node.js runs on a single thread with non-blocking I/O, simplifying development and scaling.

Additionally, Node.js uses JavaScript — a language widely used and familiar to many frontend developers, making it easier for full-stack teams.

Example of a simple HTTP server in Node.js:

const http = require('http');

const server = http.createServer((req, res) => {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello, Node.js!');
});

server.listen(3000, () => {
  console.log('Server running on port 3000');
});
