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: ["vodka", "air"]});

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

/** 4) Create many People with `Model.create()` */
var arrayOfPeople = [
  {name: "Frankie", age: 74, favoriteFoods: ["Del Taco"]},

  Person.create(arrayOfPeople, function (err, people) {
    if (err) return console.log(err);
    done(null, people);
  });
};

/** 5) Use `Model.find()` */
var findPeopleByName = function(personName, done) {
  Person.find({name: personName}, function (err, personFound) {
