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.

## `__proto__` Property

In JavaScript, objects contain a property `[[Prototype]]` that is hidden. This property either points to another object or is `null`.

The `[[Prototype]]` property of objects, i.e., `anObject.[[Prototype]]` defines the prototype of `anObject`. It is defined through the `__proto__` property which is used as a setter/getter for the `[[Prototype]]` property; i.e., `__proto__` is used in order to access/set the `[[Prototype]]` property of an object. 

## Syntax

Let's take a look at the syntax for accessing and setting the `[[Prototype]]` property of an object.
