JavaScript is one of the most popular languages used by programmers all around the world. In this course, you'll be introduced to the Object-Oriented Paradigm of JavaScript. The course will discuss OOP in both, ES5 and ES6 versions of JavaScript. It begins with a basic introduction to what Object-Oriented programming is, followed by its comparison to other languages. It then introduces the new  OOP features available in ES6 version and compares it to the ES5 version. The course then discusses objects in JavaScript followed by the use of function as objects in OOP. It goes over the interesting concepts of prototype objects, data encapsulation, and classes. It then delves into the more complex concepts of inheritance in both the versions, including prototypal inheritance, prototype chaining, method overriding and mixins. The course is filled with interesting illustrations to help in your understanding of the concepts as well as numerous quizzes and exercises to help you practice.

Learn Object-Oriented Programming in JavaScript

# Introduction
Just like other variables in JavaScript, an object also has to be defined and initialized to be created.
There are various ways to create an object. 

An *object literal* can be created:

* using the *figure brackets* `{...}` in the declaration.  

* using the `new` keyword.

* based on an existing object by using the `create()` method.

All of these approaches do exactly the same thing.

# Syntax

## Figure Brackets
We discussed earlier that an object contains data values and functions known as its *properties*. Let's take a look at the syntax for creating an object literal using `{..}`:  

var objectName = {  
  
  //properties defined
  propertyName1 : propertyValue1,
  propertyName2 : propertyValue2,
  functionName() {}
  
}

As shown above, to define a property value, the name of the property needs to be written first followed by a colon and then the property value.


A property value can be anything such as:

* *string*
* *integer*
* *boolean*
* *object* 

>**Note:** All properties are separated by a *comma*.

This lesson teaches different ways to create object literals in JavaScript.
