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.

Learn Object-Oriented Programming in JavaScript

There are various ways to access object properties. We will discuss each method in detail below.

## Dot Operator

In JavaScript, an object literal can be accessed using the **dot operator**. To access any property, the *name* of the object should be mentioned first, followed by the *dot operator* and then the *name* of the *property* encapsulated in that object.

### Example

Let's take a look at an example:

//creating an object named shape

var shape = {
  //defining properties of the object
  //setting data values
  name : 'square',
  sides : 4
}

//accessing the properties using the dot operator
console.log("Name is:", shape.name) //using dot operator to access "name"
console.log("Number of sides are:", shape.sides) //using dot operator to access "sides"

## Accessing Properties of a Nested Object

If the value of a property of an object is another object, how will it be accessed? The method is exactly the same with the addition of just one more dot, i.e., object name followed by dot operator followed by the second object name, then the second dot operator and lastly, the name of the property.


### Example

Let's take a look at an example for accessing the property of an object nested inside another object.
