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.

# Adding Properties

In this lesson, we will look at how to add properties to the *prototype* object of a *constructor* function.


## Syntax
Here is how *properties* can be added to a *constructor function* using the *prototype* property:


ConstructorFunctionName.prototype.PropertyName = PropertyValue

Since the property is being defined on the *prototype* of the *constructor function*, the double dot notation has to be used to set property values. First, the prototype property is accessed using the dot notation, then the property is defined on it using the dot operator.

Similarly, the double dot notation has to be used to get the property values defined on the prototype object as well.

This lesson teaches us how to add properties and methods to an object prototype.
