JavaScript - Object

Creating a JavaScript Object

var Employee = {firstName:"John",

                lastName:"Doe",

                age:50,

                eyeColor:"Black",

                salary:"60000"};

var Employee = {
  firstName: "John",
  lastName: "Doe",
  age: 50,
  eyeColor: "blue",

  salary:"60000"
};

var Employee = new Object();
Employee.firstName = "John";
Employee.lastName = "Doe";
Employee.age = 50;
Employee.eyeColor = "Black";

Employee.salary = "60000";

JavaScript Objects are Mutable

var person = {firstName:"John",

              lastName:"Doe",

              age:50,

              eyeColor:"blue",

              salary:"60000"}

var x = person;
x.age = 10;           // This will change both x.age and person.age
