Your fs.appendFile function should have a callback function as the third parameter.
Syntax:
fs.appendFile( path, data[, options], callback )
Your JS File should change like this:
console.log("Starting app.js");
const fs = require('fs');
const os = require('os');
const notes = require('../notes-node/notes.js');
var user = os.userInfo();
fs.appendFile("message.txt", `Hello ${user.username}! You are ${notes.age}`, (err) => {
if (err) {
console.log(err);
}
});
console.log(user);
