What topics in Node.js have you studied and can you name the main materials or resources you used?

In the field of Node.js, I studied the following topics:

• Basics of working with Node.js: event loop, asynchronous programming, callback, Promises, async/await.
• Working with modules and packages via npm.
• Creating HTTP servers using the built-in http module and frameworks like Express.
• Working with the file system (fs), streams.
• Working with databases (e.g., MongoDB through mongoose).
• Error handling and logging.
• Testing (e.g., with Mocha, Jest).
• Using WebSocket for real-time communication.

Main resources I used:

• Official Node.js documentation (https://nodejs.org/en/docs/)
• Book "Node.js in Action"
• Online courses on Udemy and Coursera platforms
• Articles and tutorials on Medium, dev.to
• GitHub repositories with project examples
• Stack Overflow for solving specific problems

Example of a simple HTTP server on Express:

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

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

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