Describe your practical experience working with Node.js and the areas where you have applied this framework.

I used Node.js for developing server applications and APIs, as well as for creating automation scripts. In my projects, I used Express.js for building RESTful services, which allowed me to quickly and efficiently handle HTTP requests.

Additionally, I used Node.js for working with databases (e.g., MongoDB via Mongoose), and for integrating with external services and message brokers.

Example of a simple server on Express.js:

const express = require('express');
const app = express();

app.get('/hello', (req, res) => {
  res.send('Hello, world!');
});

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

Node.js is well-suited for high-load applications with many concurrent connections due to its event-driven architecture.
