Why is ReactJS the first choice of Front-end Web/App Developers?

by | Jun 15, 2021 | Development, Technology

In 2021 ReactJS has totally changed the scenario of web/app development by their reliable, reusable, and efficient features to develop websites and applications. ReactJS is developed by Jorden Walke, a software engineer in Facebook, as a JavaScript library for web front-end development. ReactJS has gained popularity among developers as well as business owners. ReactJS is featured among the top 5 digital skills that organizations are looking for in hiring developers.

In this blog, we are going to explain what ReactJS is, the advantages and benefits of ReactJS, and a comparison of ReactJS with its competitors.

What is ReactJS?
ReactJS is an open-source, component-based, front-end JavaScript library in the field of web development. It builds fast and interactive user interfaces for web and mobile applications. It is proven to be the best framework for building single-page applications of any size and scale. With all these attributes working out in its favor, ReactJS is all set to the job market, developer community, and technology landscape.
Today small to big organizations have relied on ReactJS and develop their web/app with the help of it. Some of the popular names in the list are Instagram, WhatsApp, Microsoft, Uber, Airbnb, Netflix, Amazon, Twitter, New York Times, Asana Shopify, Atlassian, Dropbox, Storybook, Intercom, Slack, and the count goes on.
As per the statista, JavaScript is a choice of 67% of developers, and ReactJS is the first choice of developers among all the JS frameworks. The requirement of ReactJS has exponentially increased in the last two years. As per the report, the demand for ReactJS developers has escalated by 180% compared to 2020.

The market is filled with a number of libraries and frameworks, some of them are very efficient also, which is why ReactJS becomes that popular in a short period of time. The reasons are stated below:

  1. Easy to Learn and Use
    ReactJS is much easier to learn and use. It comes with a good supply of tutorials, documentation, and training resources which makes it more informational. Any developer from a JavaScript background can easily understand, learn, and start creating apps while using React in a few days only. It is the V “view part” in the MVC (Model-View-Controller) model, referred to as, one of the JavaScript frameworks. It has the dominance of an open-source JavaScript User Interface (UI) library, which helps to execute the task in a better and efficient manner.
  2. Reusable Codes
    A ReactJS is made up of multiple elements, and each element has its own logic and controls. These elements are responsible for outputting a small, reusable piece of HTML code that can be reused wherever you need them. The reusable code helps to make your apps painless to develop and maintain. These components can be grouped/used with other components to allow complex applications to be built of simple building blocks. ReactJS uses virtual DOM-based tools to fill data in HTML DOM. The virtual DOM works a little fast as it only changes individual DOM elements instead of reloading the complete DOM every time.
  3. Fast and Responsive
    Due to the virtual DOM implementation and various rendering optimizations, the memory data structures in ReactJS are transformed into components. These ReactJS components update and reshape browsers by running the computation tasks. VDOM renders these components, elements, data, and so that they can be processed and utilized further.
  4. Performance Enhancement
    ReactJS improves productivity due to virtual DOM. The DOM is known to be a cross-platform and programming API that deals with HTML, XHTML, or XML. the most prevailing problem faced by developers when the DOM was updated, which led to slow-down the performance of the application. ReactJS has resolved this complicated issue by launching virtual DOM. The React Virtual DOM exists entirely in the memory and is a representation of the web browser’s DOM. Due to this, when we write a React component, we do not write directly to the DOM. Instead, we are writing virtual components that will turn into the DOM, leading to smoother, faster, and efficient performance.
  5. One-way Data-Binding
    Redux, the most popular framework for managing applications positioned in React, and another benefit of Redux is that it is easy to learn and master. Some values can be passed as components and rendered in HTML tags as properties. But it is hard to switch and approach them directly. However, ReactJS allows developers to approach components and directly change them by enabling the call-back function. This ReactJS quality is referred to as properties flow down and actions flow up.

  6. SEO Friendly
    JavaScript frameworks like React, Angular, Vue, etc., have an issue in dealing with SEO. Generally, search engines having problems while reading JavaScript-heavy applications and this used to be the biggest drawback of the JavaScript language. but with the consistent development in ReactJS come over the problem and now it can easily and efficiently navigate various search engines without any difficulty. It is because ReactJS applications can run on the server, and the virtual DOM will be supplying and returning to the browser as a regular web page.
  7. Native Applications
    With ReactJS the developers can build native mobile applications by reusing the codes. ReactJS assist to build not only high-end web application but also develop native mobile application either in iOS or Android by recycling the same codes, which can be changed with the help of React Native.
  8. Server-Side Rendering
    Great support for server-side rendering, making it a robust framework for content-focused applications. There are only a few browsers with low compatibility issues, less loading time, and high data security.
  9. Benefits of having JavaScript Libraries
    Due to the flexibility provided by the JavaScript Library, ReactJS has become one of the most chosen frameworks in the developer’s community. it gives space, freedom, and the way they want to work.

10. Scope for Testing the Code

ReactJS applications are extremely easy to test. developers have an option to test and debug their codes with the help of native tools.

Without being compared with peer JS frameworks, it is not fair to determine ReactJS as a winner. Other popular and in-demand JS frameworks in the market are AngularJS and Vue.JS. How does ReactJS differentiate between AngularJS and Vue.js? Here’s a quick overview: 

AngularJS Vs. ReactJS

  • AngularJS support Bi-directional data binding and ReactJS supports Unidirectional data binding, 
  • As compared to ReactJS, AngularJS is difficult to understand and learn, because it uses third-party libraries and syntax.
  • Angular is an MVC (Model-View-Controller) framework, but ReactJS is an open-source framework.
  • AngularJS works on Regular DOM and ReactJS works on Virtual DOM,

 Vue.JS Vs. ReactJS 

  • Vue uses HTML templates, while React uses JSX or JavaScript Expressions for integration of HTML and CSS into JavaScript. It is an XML and another syntax that enables developers to develop User Interface components that are independent along with view-rendering instructions.
  • ReactJS gives better support to apps which leads to faster performance than the one built-in Vue. The addition or extension of an element makes the Vue app slower to download.
  • ReactJS serves the view layer of an application that is made up of components and doesn’t have a built-in architecture design. Vue follows the View Model (VM) approach and undertakes the design on MVVM, especially while developing a large-scale application.


After going through all these points, data, graphs, and comparisons, we have concluded that the best framework should be easy to use, in-demand, reliable, efficient, easy to use, and affordable and these components are totally fit at ReactJS. 

Whether it is big or small, every organization wants to have a driver’s seat in the market, and this needs to be technologically superior and advanced to your rivals. Then only can you blow your trumpet and become the leader in your business.
