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.

## What are Mixins?

For a class to call *methods* from another class it first needs to inherit those methods. The child class extends the parent's class, inherits its methods, and then invokes them. However, there is a limiting factor: a class can only inherit from another class.

That brings us to the question: 

Is there a class whose methods can be inherited by other classes without it having to be their parent class? This where **mixins** are implemented.

A **mixin** is a class that contains various methods implementing different functionalities. Other classes can then inherit those methods without having the *mixin* class be their parent class.

>**Note:** A mixin class is not used alone. It only provides other classes with extra *methods*.

## Syntax
