Object example
The object 
cat
combines attributes and behaviors of a cat in the following object
let cat = {
    age: 4,
    name: 'Bella',
    meow() {
        console.log('Meowwww');
    }
}
Instead of the object, we would have separated function and variables, which is not organized way
let catName = 'Bella';
let catAge = 4;

function meow() {
    console.log('Meowwww');
}

Nested objects
It's possible to have an object inside another object. In the example we have object 
boyfriend
inside 
cat
object
let cat = {
    name: 'Lucy',
    age: 4,
    meow() {
        console.log('Meowwww');
    },
    boyfriend: {
        name: 'Jack',
        age: 5,
        favoriteColors: ['Green', 'Yellow'],
        meow() {
            console.log('Meeoowwwwwwwwwwww');
        },
    }
}
Accessing nested object's attributes and methods:
console.log(cat.boyfriend.name); // Jack
cat.boyfriend.meow(); // Meeoowwwwwwwwwwww
