1. Digitizing People. I have doubt in this. Please help me


#1
var bob = {
    firstName: "Bob",
    lastName: "Jones",
    phoneNumber: "(650) 777-7777",
    email: "bob.jones@example.com"
};

var mary = {
    firstName: "Mary",
    lastName: "Johnson",
    phoneNumber: "(650) 888-8888",
    email: "mary.johnson@example.com"
};

var contacts = [bob, mary];
console.log(contacts[0]);

// printPerson added here
var printPerson = function (person) {
    console.log(bob.firstName + " " + bob.lastName);
    console.log(mary.firstName + " " + mary.lastName);
}
