Object Oriented Programming in JavaScript

Object-Oriented Programming (OOP) is a programming paradigm that organizes code into reusable objects that encapsulate data and behavior. JavaScript supports OOP principles through its object-oriented features. Here are the key aspects of OOP in JavaScript:

1. Object
2. Classes
3. Abstraction
4. Encapsulation
5. Inheritance
6. Polymorphism

Let's dive deeper into each concepts through some examples:

Objects are the fundamental building blocks in JavaScript. They are created using constructor functions, object literals, or the "class" syntax introduced in ECMAScript 2015 (ES6).

For example:

// Constructor function
function Person(name)
{
    this.name = name;
}
// Object literal
const obj = { key: value };
//ES6 class syntax
class Animal {
    constructor(name)
    {
        this.name = name;
    }
}
