Gain insights into writing cleaner, modular, scalable JavaScript code through OOP. Explore basics to advanced concepts like prototypal inheritance, method overriding, and ES6 features.

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.

## Defining Methods in a Class
A class `constructor` encapsulates all properties and methods. However, methods can also be defined outside the `constructor` in a class.


Whenever a method is declared inside a class, it gets defined on the **prototype** of that class. Hence, whenever an object instance accesses a method, it gets taken from the respective class's *prototype*.

Let's take a look at how that is done.

### Example

The following example demonstrates how to define methods outside of the `constructor` in a class:

This lesson teaches us how to define methods inside a class and explains the use of get/set methods in classes.
