Object Creation using create():
==============================
Syntax:
	Object.create()

const Vehicle = {
    type : 'Vehicle',
    startEngine: function(){
        console.log('Engine Started!');
    },
    stopEngine: function(){
        console.log("Engine Stopped!");
    }
};

console.log(Vehicle.type)

const Car = Object.create(Vehicle);

Car.type = "Car"; // existing property
Car.numWheels = 4; // new property
Car.drive = function(){
    console.log("Driving the car in autmatic mode...");
}

console.log(Car);
Car.drive();
Car.startEngine();
Car.stopEngine();
=======================================================
Accessing Object Properties:
============================
1) using . operator:
====================
Syntax:
	Object-name.property-name

2) using []:
===========
Syntax:
	Object-name['property-name']

3) using Iterators:
====================
for in:
======
==> used to access the property names from the given object.
Syntax:
	for(var obj in Object-name){
		//logic
	}

for of:
======
==> not possible to access values

const Employee = {
    name : "Jatin",
    type : "Full-time",
    shift : "ganeral-shift",
    salary : 67785.0,
    project:[
       {client:"Samsung",domain:"Telecom",location:"Bangalore"},
       {chipset:"Quad2553",product:"Qualcom"}
    ]
}

// Access the object properties
console.log(Employee.name);
console.log(Employee.type);
console.log(Employee.shift);
console.log(Employee.salary);

//using []
console.log(Employee['name']);
console.log(Employee['type']);
console.log(Employee['shift']);
console.log(Employee['salary']);

// for in iterator
for(let obj in Employee){
    console.log(obj);
}

========================================
// Ecommerce Order
const order = {
    orderId : 12345,
    customer: {
        name : "Manikanta",
        email : "mani1122@gmail.com",
        address : "1-1-11, XYZ Stree, USA"
    },
    items : [{name:"Laptop",price:39999.0,quantity:1},{name:"Mouse", price: 2000.0,quantity:2},
    {name:"Hoody", price: 1999,quantity:3}],
    isPaid : true
}

order.items.forEach(item=>{
    console.log(`Item:${item.name}, Price:${item.price} and Quantity:${item.quantity}`);
});

=====================================
ADDING NEW PROPERTIES INTO AN OBJECT:
=====================================
Syntax:
	Object-name.newPropertyName = value;

DELETING PROPERTIES FROM OBJECT
===============================
Syntax:
	delete objectName.PropertyName;

OBJECT PROPERTY MODIFICATION:
==============================
Syntax:
	Object-name.propertyName = new-value;

const Student = {
    name : "Rakesh",
    age : 17
}
// modify property value
console.log(Student)
Student.name = "Kalyan";
Student.age = 18;

console.log(Student);

// adding new properties
Student.roll = 10;
Student.subject = "Maths";
console.log(Student)

// deleting the object property
delete Student.age;
console.log(Student);
