Why Use React? – A Detailed Overview

Share this article


A crucial part of web development is using front-end libraries and frameworks. Using libraries has become essential for creating high-performing responsive web pages and web-based apps. One such front-end web development tool for programmers is ReactJS, which is utilized by around 10.2 million websites globally.

Because of how quickly the digital world is developing, new libraries are released every year. So it makes sense that choosing the library or framework for a project might be complex. This blog discusses one such front-end web development technology, React.

This article will go through some ReactJS highlights that make it stand out. But first, a quick explanation of ReactJS and why it's used in web development.

React.js: What is it?

An open-source JavaScript framework and library called React.js was created to rapidly and effectively construct dynamic user interfaces and online apps with much less coding.

React is the most appropriate choice since it is a very declarative, quick, and adaptable JavaScript library. To create intricate user interfaces, you may utilize "components," which are small, self-contained bits of code. In addition, it regulates how web applications' view layer is used. As a result, react is extensively used in web development even though it is more of a library than a language.

Some of front-end programming's most perplexing problems are easily resolved with ReactJS, which makes it simple to develop dynamic, interactive online programs. In addition, a robust developer community is swift, scalable, adaptable, potent, and expanding quickly. 

Finding a platform today that is easy to use, has an efficient developer interface, has clear abstractions, and produces virtual DOMs relative to other platforms is difficult. In addition to this, ReactJS is a development platform that may provide a lot more than typical. Therefore, it is crucial to comprehend the benefits of adopting ReactJS for your next development project.

Why Use React?

Utilizing React, which is a component of JavaScript, has several benefits. React-built products are easy to scale, and one language is utilized for server, client, and mobile sides, resulting in great productivity, teamwork-friendly workflow patterns, the UI code being legible and maintainable, and more. 

As a result, React and industry leaders utilized other JS technologies in some of the most innovative, market-defining products available today. However, let's take a closer, more in-depth look at some specific justifications for using React and, more crucially, when to utilize React.js to take on the most appropriate objectives and produce excellent outcomes.

Features of React.js

1. Mature, easily understandable dev workflow

The library's eventually optimized code language and development interface are among the primary justifications for using React.js for web development. React's API reinforces Lightweight, fast performance characteristics to enable a hassle-free, efficient development approach. 

In addition, because React's principles and components are so easy to understand, there isn't much of a learning curve involved. There aren't as many extra HTML properties as there are with other popular frameworks like Angular and Vue.

2. Absolute adaptability and compatibility

React.js is one of those technologies that allows you to easily reuse across various platforms once you get the hang of it. Thus using it for web development may prove to be quite useful. But, of course, all of this is a result of being a natural library, with the main objective of producing distinct web design features and components.

Additionally, the broad, well-established community makes a big contribution. As a result of the breadth of the React ecosystem today, developers can now create desktop, mobile, and static websites, manage server rendering and incorporate cutting-edge tech ideas with online solutions using the same simple react web development principles.

3. Uncomplicated component reuse

Different components may be designed using React.js. Building components, therefore, can be easily reused for other projects. The unique object you receive after creating a React.js web application element may be added to any other project that can use the React-based code.

Those parts work together to form a larger overall hierarchy, but each has its internal logic and rendering basis. As a result, it offers excellent scalability potential, aids in achieving much greater consistency in React online apps, and simplifies further support and optimization.

4. Virtual DOM reinforces high performance

React has incredibly fast rendering capabilities, with all view changes instantly reflected in the virtual DOM by virtualizing and maintaining DOM in memory. Comparing prior and present virtual DOM states, the customized differential approach may effectively decide how to apply changes while requiring the fewest updates possible.

The quickest read/write time is then achieved by introducing a minimum amount of updates, which improves overall speed. Systems are slowed down by DOM modifications, which are intelligently reduced and optimized by virtualizing DOM. 

The fact that all virtual DOM modifications take place "behind the scenes," or internally and independently, also makes it possible to reduce the pace at which hardware resources are consumed dramatically.

5. Flux and Redux's abilities

The Flux and Redux capabilities that React provides out of the box also make it a particularly popular choice for web development. The Flux-based software architecture was initially presented by Facebook's developers, who improved conventional React components with unidirectional data flow capabilities and provided a more effective organization of tasks.

Consequently, the coordination of produced activities and store updates is done by a central dispatcher. Following that, it adjusts the views in line with store changes. After that, all data stays in storage; no duplicates are created, allowing you to maintain model data synchronization without going far.

On the other hand, Flux can only be used as a front-end architectural pattern for a productive UI design workflow and not as a full-fledged library. It is because it gives a single store object to handle all app data, which makes manipulating the underlying data easy and hassle-free. Furthermore, the view is kept in sync with the relevant data components, while renders are triggered when the store changes.

6. Extensive toolkit at your disposal

Among other things, our experts emphasize an excellent toolset and tech stack to explain why we choose React JS for web development. You can easily install and utilize Redux Development Tools and React Developer Tools as standard Chrome extensions, providing incredibly useful features. 

They enable you to effectively investigate React-based hierarchy components, validate dispatch operations, and instantly see state changes in the extension. Additionally, hosting, graphic editing tools, and other tools may be added to or built for your website using content management systems for marketers.

7. Strong Community Support

React has a large and supportive community, which is one of the key reasons you should use it for your project. Every day, various unique React engineers work to build a more reliable front-end framework. 

Currently, React JS has 189k GitHub stars and 38.9k active contributors. In addition, react lessons are also available in abundance on YouTube and informative publications written by professionals and experts.

8. The Virtual DOM

The virtual DOM is one of React's most intriguing features. But first, you should consider how the app's structure may impact performance when developing an app with lots of user interaction and data changes. 

For example, performance can get congested due to intensive DOM manipulation. Even worse, because the DOM is organized like a tree, little modifications at the root can significantly affect others.

React uses a virtual DOM to address this problem. 

The virtual DOM, stored in memory rather than displayed on your screen, is where changes to a new view are first made. The most effective way to make these updates is determined, and only those alterations are made to the actual DOM. It guarantees that the real DOM is updated as soon as possible, improving efficiency and providing a cleaner user interface.

9. Special React hooks

React.js 16.8 introduces hooks, a new feature that enables authors of JavaScript to extend function components with states and other features. No more challenging coursework will be required of you. 

When determining whether to use React for developing web applications, hooks make it straightforward to manage state logic between components, combine similar logic into a single component, and transport data between components without props or classes.

10. SEO-Friendly:

 As you may already be aware, the success of any online business depends on how effectively it is optimized for search engines. ReactJS also has the advantage of working around search engines' frequent inability to understand JavaScript-heavy apps. In addition, react significantly quickens the loading of websites, allowing them to take over the top page of Google's search engine results.

React has several frameworks, including NextJs, one of which helps with SEO. Since NextJs moves rendering to the server, the client can no longer conduct data processing. In addition, there is less JS to load since the server pre-renders the pages before providing the final HTML to the client, which enhances speed and SEO.


React is a great option for developers searching for a simple-to-use and highly effective JavaScript framework since it offers cutting-edge capabilities. With JavaScript-driven pages and React, you can quickly create intricate UI interactions connecting with the server. So bid farewell to pointless full-page reloads and begin using React while creating.
