# 6. We Made a Friend!

Hello. I am checking other peoples solution to this last exercise and it seems that everyone did it differently then me. This solution was accepted but i just want to know if my way should be used or should i follow the "mainstream" solution with:

contacts[contacts.length] = {
firstName: firstName,
lastName: lastName,
phoneNumber: phoneNumber,
email: email
};

and why?
Below is how i did it.

``````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];

function printPerson(person) {
console.log(person.firstName + " " + person.lastName);
}

function list() {
var contactsLength = contacts.length;
for (var i = 0; i < contactsLength; i++) {
printPerson(contacts[i]);
}
}

/*Create a search function
then call it passing "Jones"*/
function search (lastName) {
var contactsLength = contacts.length;
for (var i = 0; i < contactsLength; i++ ) {
if (contacts[i].lastName === lastName) {
printPerson (contacts[i]);
};
};
};

function add(firstName, lastName, phoneNumber, email) {
this.firstName = firstName;
this.lastName = lastName;
this.phoneNumber = phoneNumber;
this.email = email;

contacts[contacts.length] = this;
};

list();``````

Can we see your solution, so we can understand what you might've been missing?

I posted my entire solution in my first post but the part that is different from others is this:

function add(firstName, lastName, phoneNumber, email) {
this.firstName = firstName;
this.lastName = lastName;
this.phoneNumber = phoneNumber;
this.email = email;

``````contacts[contacts.length] = this;
};``````

and in several examples i have seen people do it this way:

contacts[contacts.length] = {
firstName : firstName,
lastName : lastName,
phoneNumber: phoneNumber;
email: email
};
}

Hi! I actually solved just like you as well, with the "this"!

But I think the other solution follows their example:

contacts[contacts.length] = {
firstName: firstName,
lastName: lastName,
phoneNumber: phoneNumber,
email: email
};

Maybe that's why people used too =)

So basically it is the same thing just done in a bit different way. Thanks.
