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:
- Object
- Classes
- Abstraction
- Encapsulation
- Inheritance
- Polymorphism
Let's dive deeper into each concepts through some examples:
Objects
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;
}
}
