What are some examples of using Node.js modules?

Node.js has a variety of built-in modules. For example, the 'fs' module is used for file system operations.

Can you give me a code snippet using the 'fs' module?

Sure! Here's a simple example:

const fs = require('fs');
fs.readFile('example.txt', 'utf8', (err, data) => {
  if (err) throw err;
  console.log(data);
});

What other modules should I know about?

You should also look into the 'http' module for creating servers, and 'path' for handling file paths.

How do I install third-party modules?

You can install third-party modules using npm. Just run npm install <module-name> in your project directory.
