Creating Objects

const person = {
    name: 'Alice',
    age: 25,
    greet() {
        return `Hi, I'm ${this.name}`;
    }
};
    

Accessing Properties

// Dot notation
person.name         // 'Alice'

// Bracket notation (for dynamic keys)
const key = 'age';
person[key]         // 25

// Check if property exists
'name' in person    // true
