添加地址簿的功能

Question

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 add(firstName,lastName,email,phoneNumber)
{
}

我不知道如何以及在add函数中写什么来帮助我添加更多联系人。请帮我！感谢

Answer 1

function add(firstName,lastName,email,phoneNumber) { 
        var test_user=
        {
        "firstName": firstName,
        "lastName":lastName,
        "phoneNumber": phoneNumber,
        "email": email
      };

        contacts.push(test_user);

        }
