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

## Introduction
If you are familiar with languages such as **C#** and **Java**, then you must have heard the term *Object-Oriented Programming* (OOP). You might have an idea of OOP and how it relates to classes and objects. Before we delve into those details, let's take a look at the definition.

## Definition
**Object-oriented programming** is a style of programming, not a tool, which is why despite being old, it's very popular and widely used. This style involves breaking a program into segments of *objects* that can communicate with each other. Each object is defined by its own set of *properties*. These properties can then be accessed and modified through various operations.
### Example

#### Explanation
The above illustration gives a real-life example of an employee record in which each employee can be considered an "object". Since every employee has a *name*, *age*, and *designation*, these can be considered the *properties* of that employee.
