ReferenceError: 'firstName' is undefined


`

Replace this line with your code.

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"*/
var search = function(lastName){
var contactsLength = contacts.length;
for(var i =0; i < contactsLength; i++){
if(contacts[i].lastName === lastName){
printPerson(contacts[i]);
}
}
};
search("Jones");
add[contacts.length] = {
firstName: firstName,
lastName: lastName,
phoneNumber: phoneNumber,
email: email
};

var add = function(firstName, lastName, phoneNumber, email) {
contacts[contacts.length] = {
firstName: firstName,
lastName: lastName,
phoneNumber: phoneNumber,
email: email
};
};
add("Abdul", "Hamid", "079-626-8020", "example@gmail.com");

list();
