Well, Callback Hell

const fs = require('fs');

fs.readFile('readMe.txt', function(err, data) {
    if (err) throw err;
    else {
        let textFromFile = data.toString();
        fs.mkdir('./moved', function (err) {
            if (err) throw err;
            else {
                fs.writeFile('./moved/writeMe.txt', textFromFile, 'UTF-8', function(err) {
                    if (err) throw err;
                    console.log('Done!');
                });
            }
        });
    }
});
