Learn to write cleaner, more modular, and more scalable code in JavaScript by gaining mastery of Object Oriented Programming (OOP). 

You'll start with the basics of object-oriented programming and build up to more advanced concepts such as prototypal inheritance, prototype chaining, method overriding and mixins. Along the way, you'll learn how each concept applies to JavaScript's sometimes unique way of handling things. You'll also see how various JavaScript features make it particularly convenient for OOP, with particular emphasis on changes introduced in ES6.

This course is filled with hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.

## Inheritance Using Constructor 

Objects are inherited from the constructor function’s prototype object using the prototype chain. The same concept could also be used in the implementation of class-based inheritance, i.e., where one class inherits the properties (including methods) from another class.

This lesson teaches us how class-based inheritance is implemented in the ES5 version by using constructor functions.
