JavaScript Prototype Inheritance & ES6 Class - JavaScript Bangla ( বাংলা ) Tutorial

JavaScript is a Prototype based language. It has no class implementation in its core. That's why Inheritance in JavaScript is also based on Prototype. Unlike other Object Oriented programming languages like Java, in JavaScript we make objects from Constructors instead of Class. This is the fundamental difference between JavaScript and other Object Oriented Programming Language.

In this tutorial, I have explained how Inheritance is achieved in JavaScript based on Prototype. While doing so, I have explained important concepts like Prototype Chain, Master Object, Constructor and then explained recent ES6 class syntax, it's properties & methods, Static Method, Getter-Setter and Polymorphism.

This video is a continuation of my previous video on Prototype -    • Prototype - the foundation of JavaScript -...  . I would highly recommend to watch that video before and then come back to this video because I have used certain references from that video.
