React is a framework released by Facebook for creating Single Page Applications (SPA). What is a Single Page Application? Most web applications are traditionally server-side applications. The server holds the business logic, stores data, and renders the website to the client. When a client clicks on a link, it sends a request to the server, and the server will handle this request and send back a response with HTML code which the browser will render and be viewed by the user. 

The problem here is that with this approach, the server receives a lot of requests. For example, when we go to a website and click on its Home page, we send a request for which the server has to respond. We click on the About page and it sends another request, and the server responds. We click on Blog and it sends another request and again the server responds. Essentially, traditional websites consist of independent HTML pages and when a user navigates these pages, the browser will request and load different HTML documents. 

The many requests, response incurs a lot of time and resources spent on these tasks lead to a slow feeling of web pages, whereas the apps on your mobile phone or desktop feel very fast most of the time. 

React wants to bring this app like feeling to the browser where we don’t always have to load new pages each time there is an action from the user. A user still clicks on various links in a SPA. 

However, this time, the client handles the requests on its own and will re-render the HTML page through Javascript, so the server is left out here if no data from the server is needed. This is much faster as we don’t have to send data over the Internet. The client doesn’t have to wait for the response, and the server doesn’t have to render the response. 

Also, in a SPA, the browser loads one HTML document and when users navigate through the site, they stay on the same page as Javascript unloads and loads different views of the app onto the same page itself. 

The user gets a feeling that she is navigating through pages but is actually on the same HTML page. Facebook newsfeed is a good example. Other examples are Instagram or Twitter where the content gets dynamically refreshed without requiring you to refresh or navigate to a different page. 

Manipulating DOM Elements Efficiently Loading and unloading different views of the same page involve querying and manipulating DOM elements. Such DOM operations involve adding children, removing subtrees, and can be really slow. 

This is where React addresses this shortcoming in manipulating DOM elements efficiently. React does this by updating the browser DOM for us. With React, we do not interact with the DOM directly. We instead interact with a virtual DOM which React uses to construct the actual DOM. 

The virtual DOM is made up of React elements that look similar to HTML elements but are actually Javascript objects. It is much faster to work with Javascript objects than with the DOM API directly. We make changes to the Javascript Object (the virtual DOM) and React renders those changes for us as efficiently as possible. 

Asynchronous Operations In times when we need to get or send data from/to the server, we send a request to the server. But these are mainly restricted to initial loading and necessary server-side operations like database operations. Besides these operations, we will not frequently need to request from the server. And if we do make server requests, we do it asynchronously, which means we still re-render 

the page instantly to the user and then wait for the new data to arrive and incorporate it and re-render only the required view when the data arrives; thus providing a fluid experience. 

Thinking in Components A React app is made up of components. For example, if we want to build a storefront module like what we see on Amazon, we can divide it into three components. The search bar component, sidebar component, and product component. A React component contains a JSX template that Components can also contain other components. For example, in products component where we display a list of products, we do so using multiple product components. Also, in each product component, we can have a rating component 

StackOverflow Developer Survey Results 2020 


Most Loved, Dreaded, and Wanted Web Frameworks

In 2020 ReactJS Ranked 1st on Awareness, interest, and satisfaction ratio rankings, and also in opinions on the technologies survey

React JS — The Need & Key Benefits

Majorly leveraged to build rich user interfaces of web and mobile applications, ReactJS works on the concept of MVC.

It needs just a basic understanding of HTML and JavaScript, that is the prime reason it has gained so much popularity as a front-end web development tool.

Undoubtedly, when the popularity charts for ReactJS are soaring high, there ought to be certain key reasons why developers love this framework to such an extent. Though the list is quite a big one, here are the most significant features and benefits that it offers, that makes it a desirable technology by one and all:

Faster Go-To-Market Time

Organizations are keen to adapt to technologies that assist them in fastening their time to go to market, complete their software solutions on time and implement them without any hassle. ReactJS is just perfect for this since it has a high development speed because of its multiple reusable components.

Developers find it easy and manageable to build applications at a great speed. It ensures high-end productivity and accelerates maintenance. React also has React Native, a cross-platform mobile app development tool that works wonders.

A Secure Future

With technologies coming and going so haphazardly, the need for a stable technology is what organizations are looking for. And, ReactJS is just that, since it is backed by big names like Facebook, Instagram and millions of developers globally.

Even, with peer competition increasing, ReactJS has been able to sustain its popularity level and in fact, has been soaring high still. Hence, developers find security and stability in opting for React.

Ease Of Use

With so many tools and frameworks doing the rounds, what developers get attracted to is the simplicity with which the tool operates.

ReactJS has turned to be an easy option for novices and experts, alike. It has not only streamlined the job of programming but has also simplified resource administration to a great level.

Quick Rendering With V-DOM

The Facebook team has given Virtual Document Object Model (V-DOM) to ReactJS because of which it offers a high-speed rendering, less time wastage, enhanced user experience and better app performance. This is mainly for highly complex and dynamic applications.

Efficient Design And Developer Tools

React comes loaded with a great set of effective design, developer and debugging toolset. React developer tools are there for certain browsers like Chrome and Firefox. These empower developers to undergo inspection in the V-DOM. Even tracking of the hierarchy of components is possible.

Clear AbstractAs one of its key advantages, ReactJS offers a good level of abstraction that signifies that none of the complicated internal processes is exposed to the users.

Much so, because it is not needed too. Internal processes better stay away from the end-users to lessen the confusion and that is possible by using ReactJS.

The development team, who is using ReactJS, needs to have a proper understanding of the complete life cycle of the components and need not always follow any pattern base like MVC.
