// 1: WHAT ARE OBJECTS?

const person = {

name: "John",

age: 25,

isStudent: true

};

// 2: WHY USE OBJECTS?

const personName = "John";

const personAge = 25;

const personIsStudent = true;

// 3: OBJECT LITERAL - THE STANDARD WAY

const car = {

brand: "Toyota",

model: "Corolla",

year: 2022,

color: "Silver"

};

console.log(car);

const book = {};

console.log(book); // Empty object

// 4: OBJECT CONSTRUCTOR - THE OLD SCHOOL WAY

const student = new Object();

student.name = "Sarah";

student.age = 22;

student.major = "Computer Science";

console.log(student);

const teacher = new Object({

name: "Mike",

subject: "Math"

});

// 5: LITERAL VS CONSTRUCTOR - WHICH ONE TO USE?

// Object Literal - Modern, Preferred

// const product1 = {

// name: "Laptop",

// price: 999

// };

// Object Constructor - Old School, Avoid

// const product2 = new Object();

// product2.name = "Laptop";

// product2.price = 999;

// 6: PRACTICAL EXAMPLES

// Example 1: User Profile

const user = {

username: "john_doe",

email: "john@example.com",

age: 28,

isActive: true,

followers: 1250

};

console.log(user);

// Example 2: Product in E-commerce

const product = {

id: 101,

title: "Wireless Headphones",

price: 79.99,

inStock: true,

rating: 4.5

};

console.log(product);

// Example 3: Blog Post

const post = {

title: "Introduction to JavaScript Objects",

author: "Jane Smith",

date: "2025-10-19",

views: 3420,

published: true

};

console.log(post);

// 7: OBJECTS CAN HOLD ANYTHING

const company = {

name: "Tech Solutions",

founded: 2020,

employees: 150,

departments: ["Engineering", "Sales", "HR"],

ceo: {

name: "Alice Johnson",

age: 45,

experience: 20

}

};

console.log(company);

console.log(company.departments); // Array inside object

console.log(company.ceo.name); // Nested object property
