How to copy a file quickly in Node.js?

To copy a file quickly in Node.js, we can use the fs.copyFile method.

fs.copyFile('source.txt', 'destination.txt', (err) => {
  if (err) {
    throw err;
  }
  console.log('source.txt was copied to destination.txt');
});

to call copyFile with the path of the file to copy, the path to copy to, and a callback that’s run copyFile is done.
