Code for myApp.js

/** 1) Install & Set up mongoose */

const mongoose = require('mongoose');
mongoose.connect(process.env.MONGO_URI);

/** 2) Create a 'Person' Model */
var personSchema = new mongoose.Schema({
  name: String,
  age: Number,
  favoriteFoods: [String]
});

/** 3) Create and Save a Person */
var Person = mongoose.model('Person', personSchema);

var createAndSavePerson = function(done) {
  var janeFonda = new Person({name: "Jane Fonda", age: 84, favoriteFoods: ["eggs", "fish", "fresh fruit"]});

  janeFonda.save(function(err, data) {
    if (err) return console.error(err);
    done(null, data)
  });
};

Could someone explain how this function works? It don’t see what “data” will be other than undefined or how it works.

janeFonda.save(function(err, data) {
    if (err) return console.error(err);
    done(null, data)
  });

So the content of janeFonda gets assigned to data? I don’t understand how these kind of assignments work, could you tell some resource where I could learn how that works?
