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.

Learn Object-Oriented Programming in JavaScript

In this lesson, we will learn about the major concept of **"Prototype Objects"** in JavaScript.

Before we get into how it can be used, let’s discuss what a *prototype* is.

## Prototype Properties in Objects

Instead of jumping directly into the definition, let’s begin by looking at the code below:
