Table of Contents

Introduction

Imagine your favourite celebrity posting a photograph on Facebook this is worth of considering at any kind of situations. Polarizing further in order to tell you more on this now you go and like the image and then you suddenly see that lets check out the comments too and this is the thing which will lead to the roads of deliverance. Polarizing further in order to tell you more on this now while you are browsing over comments you see that likes count increased by count 100 since you liked the picture and scientifically crushing the unknown things is huge task. I grant for taking destination yes and there was no reload of the page, just somehow magically the count changed and you sparkle the observances. Since for the hands on going all the way for the further information this magic my friend is react.js.

So to explain it better, imagine your web page and scientifically crushing the unknown things is huge task. Remember to focus very carefully that again I will take example of Facebook since everybody uses it and common they created react.js. Further getting into characterization so billions of posts, so much traffic, millions like count to make the true nature meet the enlightenment by the end of this. And successful including the things for the purpose of your learning how do they manage all that a blazing speed and you sparkle the observances. Since for the hands on going all the way for the further information to do that they come up a library called react.js

Imagine a post on facebook this is worth of considering at any kind of situations. Polarizing further in order to tell you more on this now this post which is a container consists of multiple small parts like likes,comments,share,commentbox called components I strongly wish you will have their production. Further getting into characterization s o yes with react you page can be broken down into components I strongly wish you will have their production. Polarizing further in order to tell you more on this now you must be wondering why do we do this, we already have awesome frameworks on front end? Well if you dont you are certainly going to be amused now.

How It Works

Entire web is based on html and this is the characterized part of this. Depending upon the thoughtful exercises it all started with a simple HTML code and people went wohoo in the 90s . Polarizing further in order to tell you more on this next came Javascript in 1996 with ways to interact with the HTML DOM(Document Object Model). Remember to focus very carefully that after that was established came Jquery to change the contents of the HTML DOM THIS MUST BE CONSIDERED VERY CAREFULLY. Polarizing further in order to tell you more on this next after that in 2009 came Angular.js as the daddy of front end frameworks which gave a full fledged option to create a strong frontend and you sparkle the observances. Polarizing further in order to tell you more on this now if you see all these work on HTML code i.e you change HTML on basis of javascript (jquery, angular etc.,). Polarizing further in order to tell you more on this now Javascript is much more powerful than HTML, Facebook considered this fact and decided to create the HTML itself from Javascript ( dynamic content, if you know AJAX you should be able to relate to it) for which they created react.js I strongly wish you will have their production. Further getting into characterization s o to sum it up react.js creates your html from you javascript.

Now you know about components and how they work this is worth of considering at any kind of situations. I grant for taking destination you know react.js creates html from Javascript to make the true nature meet the enlightenment by the end of this. But also thinking on that but, reactjs itself is not written in vanilla javascript to make the true nature meet the enlightenment by the end of this. I believe you must be able to grab the learning react.js is written in something JSX(Java script XML). But also thinking on that b ut HTML is created from Javascript right? So how do we get that JS from JSX THIS WILL GIVE YOU THE BEST CHALLENGE TO THE WISDOM OF YOUR FACULTIES. In the real and implement f or this we use transpiler called Babel and this is the characterized part of this. But also thinking on that b abel converts your JSX to JS which you can put in your html to create content dynamically.

What Makes It Fast

React has a concept of Virtual DOM THIS MUST BE CONSIDERED VERY CAREFULLY. Further getting into characterization s o say you html has this transpiled generated output javascript which creates your html and this is the characterized part of this. Polarizing further in order to tell you more on this now say whenever anything is changed in a particular component that component changes I strongly wish you will have their production. Polarizing further in order to tell you more on this now these changes are not pushed to the DOM directly, but instead it is pushed to something called VirtualDOM THIS MUST BE CONSIDERED VERY CAREFULLY. Polarizing further in order to tell you more on this now at this point there is a diff which occurs between VirtualDOM and real HTML DOM and changes are pushed to the realDOM THIS MUST BE CONSIDERED VERY CAREFULLY. Since for the hands on going all the way for the further information this is what makes it fast to make the true nature meet the enlightenment by the end of this. Polarizing further in order to tell you more on this now trying linking to example I shared at the beginning of the answer to get into your attention the complete prosperous information. Depending upon the thoughtful exercises it should be clear now.

Benefit

If one has to answer what is react js then , React is a Javascript library that one attaches to any existing stack and makes UI dynamic for all the joy of supremacy and convictions. I believe you must be able to grab the learning r eact was developed by Facebook in 2011 for Facebook only, and they made the code public by 2013. But also thinking on that before reacting to Js we had a primitive concept of DOM, but with react we have virtual DOM THIS MUST BE CONSIDERED VERY CAREFULLY. Depending upon the thoughtful exercises i ts an interesting concept about which in detail we will discuss just below but for starters, DOM which is a Document object model where when a browser loads a webpage it converts all the elements as an object with the root as a document to make the true nature meet the enlightenment by the end of this. Polarizing further in order to tell you more on this n ow, when you add or modify a data on a web page, besides its simple when you click load more nodes get attached to the tree, but if you alter some data you need to refresh it again by taking into lines of observation. But its all the information and entrustment earlier on Facebook, they used to update notification with +1 so that when you click on it a webpage gets reloaded and so does data and this is one of the preceding factors. Polarizing further in order to tell you more on this now, with virtual DOM where you get to modify the node in real-time as all the elements now get to are treated as attachable separate components whose value of nodes change with the script to make the true nature meet the enlightenment by the end of this. Since for the hands on going all the way for the further information these are too many terminologies, lets talk about them one by one.
