Object Oriented Programming in Javascript Tutorial

Object Oriented Javascript Tutorial

Hello, All as the title suggest we are going to understand what is object-oriented in JS. 

for those we don't have knowledge about Object Oriented Programming language, let's understand the terminology out OOP Language.

OOP language is totally based on objects where the objects contain data, methods, and its attributes.

let's take a realtime example as follows:

I have fruits which are as follows as Banana, Orange, Lemon, Apple, Mango etc, so if I want to find a number of fruits I have then I can use length function to find out.

The same way in  Javascript fruits array is an object which has some properties and methods like 

length is a property of array and sort is the method of an object.

Nowadays, the Object-oriented Programming language is the more popular style for the programming language, and Javascript has taken the OOP concept from the scratch only.

If we go deep in Javascript's functions we will get the idea that Javascript already using the Object-oriented style, and everything in Javascript is an object.

But there is also one point we need to understand not all things are an object in Javascript.

There are some other things are there as well which we call as primitive types. 

Like string, boolean, null etc are primitive types.

let's check null,

null don't have any method or property so we cant expand it, so this way there are some other primitive types are there in JS.

Conclusion:

So in shorts, everything in javascript is an object, and we use OOP concepts in our coding using some OOP terminologies which we will discuss later on this series.

So click here to understand what is mean by Objects in Javascript.
