How to write files in Node.js?

To write files in Node.js, we can use the fs.writeFile method.

For instance, we write

const fs = require('fs');

fs.writeFile("/tmp/test", "Hey there!", (err) => {
  if (err) {
    return console.log(err);
  }
  console.log("The file was saved!");
});

to call fs.writeFile with the path to write the file to, the file content string, and a callback that’s run when writeFile is finished running.

If there’s an error, then err will be set.
