What methods or functions are used to read data from files via the FS module?

In Node.js, the fs module provides the following methods for reading data from files:

• fs.readFile(path, [options], callback) — asynchronous file reading, returns content in the callback.
• fs.readFileSync(path, [options]) — synchronous file reading, returns content directly.
• fs.createReadStream(path, [options]) — creates a stream for reading the file in parts.

Example of asynchronous file reading:

const fs = require('fs');

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