Why You Should Use React.js For Web Development

React.js has gained immense popularity in the world of web development, and for good reason. If you’re new to React.js or still contemplating whether to use it in your projects, this article is here to guide you through the advantages and reasons why React.js should be your go-to choice. Let’s delve into the world of React.js and explore its significance in modern web development.

A Brief History of React.js

Before we dive into why you should use React, let’s take a moment to appreciate its origin and evolution.

Facebook’s Brainchild

React.js was born within the hallowed halls of Facebook back in 2011. At the time, Facebook was already one of the largest social networking platforms globally. In 2012, Instagram, a subsidiary of Facebook, also adopted React.js for its development needs.

Open-Source Emergence

In 2013, Facebook decided to open-source React.js. Initially, it faced skepticism from the developer community due to its unconventional approach of blending Markup and JavaScript in a single file. However, as more developers experimented with it, they embraced React’s component-centric approach for separating concerns.

Industry Adoption

In 2014, numerous prominent companies started using React.js in their production environments. In 2015, Facebook open-sourced React Native, allowing developers to create native mobile apps for Android and iOS using React.js.

Stability and Growth

In 2016, with the release of version 15, React.js adopted Semantic Versioning, signaling increased stability. Today, React.js enjoys widespread usage among Fortune 500 companies, with Facebook maintaining a dedicated team for its development. They regularly release bug fixes, enhancements, blog posts, and documentation.

Why Should You Use React?

Now that we’ve traced React.js’s journey let’s explore six compelling reasons why you should consider using it in your web development projects.

1. React is Flexible

React’s flexibility is a defining feature. It’s not a framework but a library, and this library approach allows React to adapt to a wide variety of platforms. Originally designed for creating components in web applications, React has evolved to cover various use cases.

You can use React to generate static sites with tools like Gatsby, build mobile apps with React Native, and even create desktop applications for both macOS and Windows using Electron. React also supports server-side rendering through tools like Next.js and can be used to create virtual reality websites and 360-degree experiences with React VR.

One of the key mantras of React is “Learn React Once and Write Everywhere.” You can seamlessly integrate React into your existing applications, making it an excellent choice for gradual adoption and migration.

2. React Has a Great Developer Experience

Developers love working with React because of its rapid development and minimalistic API. React’s API is straightforward to learn and has only a few essential concepts.

// Example of a React Component
import React from 'react';
const Message = (props) => {
return <div>{props.text}</div>;

React uses JSX, a syntax that resembles HTML but converts React API calls into HTML elements. This approach is distinct from traditional frameworks like Angular and Vue, which embed JavaScript within HTML using custom attributes, necessitating the constant reference to documentation.

React’s simplicity and alignment with pure JavaScript and HTML provide a developer-friendly environment for creating interactive UIs. The library also offers the create-react-app package, enabling instant project setup.

3. React Has Facebook’s Support/Resources

Facebook’s deep commitment to React is evident in its extensive use within the Facebook app, website, and Instagram. With over 50,000 React components in their production environment, Facebook maintains React’s development. The top contributors to React on GitHub are full-time Facebook employees, ensuring constant updates and support.

Moreover, the React team consistently communicates with the developer community through their blog, providing detailed insights for each release. When breaking changes occur, Facebook offers Codemod tools to automate codebase updates, emphasizing their dedication to the React ecosystem.

4. React Also Has Broader Community Support

Since 2015, React’s popularity has steadily risen, boasting a massive and active community. The React GitHub repository has garnered over 164,000 stars, positioning it among the top repositories on GitHub. React’s NPM package enjoys millions of weekly downloads, indicating widespread adoption.

Reactiflux, a community tailored for React developers, boasts over 110,000 members who collaborate to solve and share React-related problems. StackOverflow, a go-to platform for developers, features over 250,000 questions related to React and its associated libraries.

Furthermore, a plethora of free and mature component libraries are available online, simplifying development. Notable examples include Microsoft’s Fluent UI, Material-UI for Google’s Material UI guidelines, and React-Bootstrap for seamless integration with Bootstrap.

5. React Has Great Performance

React addresses the performance bottlenecks associated with traditional DOM manipulation. Recognizing that JavaScript is fast but updating the DOM is slow, React minimizes unnecessary DOM changes.

React utilizes a Virtual DOM to monitor changes in component state. When a component’s state changes, React intelligently compares the existing DOM state with the new DOM structure, determining the most efficient way to update it. This approach minimizes layout trashing, which occurs when the browser recalculates the position of page elements due to DOM changes.

In an era dominated by mobile devices, efficiency is paramount. React’s design saves battery and CPU power, making it ideal for resource-conscious applications. Additionally, React boasts a compact library size, weighing in at less than 6KB (less than 3KB when gzipped), making it significantly smaller than its competitors.

6. React is Easy to Test

React’s design lends itself well to testing, simplifying the quality assurance process for your applications. Traditional UI browser testing can be cumbersome to set up, while React testing requires minimal configuration or none at all.

React testing can be performed efficiently using command-line tools, bypassing the need for browsers. This approach leads to faster test execution and the ability to run multiple test suites concurrently. Moreover, writing React tests is straightforward, thanks to tools like Jest and Enzyme.


In conclusion, React.js is a versatile and powerful tool for creating interactive applications across various platforms, including web and mobile. Its popularity continues to surge due to its flexibility, developer-friendly features, strong backing from Facebook, extensive community support, exceptional performance, and ease of testing. Embracing React.js empowers developers to excel in JavaScript, a language that dominates modern web development. When considering the ever-evolving landscape of web technologies, React.js stands out as a compelling choice for your next project.
