JavaScript Object Literals

Object literals are a way to define objects in JavaScript using comma-separated name-value pairs of properties and methods.

For example, we can define a Customer object with the syntax, which contains properties and a method GetCustomer():

var Customer = {
    firstname: "Bob",
    lastname: "Smith",
    email: "bsmith@test.com",
    phonenumber: "555-111-2222",

    GetCustomer: function() {
        return this.firstname + ' ' + this.lastname + ' ' + this.email + ' ' + this.phonenumber;
    }
}

//Print out Customer
console.log(Customer.GetCustomer());

We can also later assign properties to the object:

Customer.state = "NY";
console.log(Customer);
