Reactjs vs. React Native: Understanding the Difference Between Two Facebook Powerhouses

In the realm of modern web and mobile app development, React.js and React Native have emerged as two prominent frameworks, each with its unique strengths and applications. Both are JavaScript frameworks, but their purposes and functionalities differ significantly. While React.js is primarily used for building dynamic web applications, React Native is built for developing native mobile applications. In this article, we'll explore the key differences between React.js and React Native, also discussing their respective features, functionalities, and use cases.

ReactJS: JavaScript for the Web

React.js, commonly referred to as React, is a JavaScript library developed by Facebook for building user interfaces (UIs) for web applications. It follows a component-based architecture, allowing developers to create reusable UI components that encapsulate both structure and behavior. React.js uses a virtual DOM (Document Object Model) to efficiently update the UI in response to changes, resulting in improved performance and rendering speed. React.js is widely used for developing single-page applications (SPAs), progressive web apps (PWAs), and complex web interfaces.

React Native: Building Native Apps with JavaScript

On the other hand, React Native is an open-source framework developed by Facebook that enables developers to build cross-platform mobile applications using JavaScript and React.js. Unlike traditional hybrid frameworks, React Native allows developers to create truly native mobile experiences by rendering UI components using native platform APIs. This approach ensures that React Native apps deliver excellent performance, responsiveness, and user experience on both iOS and Android devices. React Native also provides access to platform-specific modules and components, allowing developers to leverage device features such as camera, GPS, and push notifications.

Key Differences

1. Target Platform

  • React.js is primarily used for building web applications that run in web browsers.
  • React Native is specifically designed for developing mobile applications that run on iOS and Android devices.

2. UI Components

  • React.js uses HTML-like syntax (JSX) to define UI components for web applications.
  • React Native uses platform-specific UI components provided by the underlying mobile operating systems (iOS and Android) for mobile applications.

3. Rendering

  • React.js renders UI components in the browser using HTML, CSS, and JavaScript.
  • React Native renders UI components using native APIs on iOS and Android, resulting in a truly native look and feel.

4. Development Environment

  • React.js development typically occurs in web browsers using tools like code editors, browser developer tools, and bundlers like Webpack.
  • React Native development involves using specialized development environments such as Xcode for iOS and Android Studio for Android, along with React Native CLI and Expo for managing projects.

5. Deployment

  • React.js web applications are deployed to web servers and accessed via web browsers.
  • React Native mobile applications are packaged as native binaries (.apk for Android and .ipa for iOS) and distributed through app stores.

So, Which One Should You Choose?

The choice between ReactJS and React Native depends on the type of application you're building:

1. Choose ReactJS if

  • You're building a web application with a complex and interactive UI.
  • You prioritize a large developer community and extensive resources.
  • SEO (Search Engine Optimization) is a crucial factor for your application.

2. Choose React Native if

  • You need to build a mobile application for both iOS and Android.
  • You want to leverage your JavaScript skills for mobile development.
  • Native app performance and access to device functionalities are essential.


In summary, React.js and React Native are two powerful frameworks that serve distinct domains of application development. You can leverage ReactJS for the web application and React Native for the mobile app, ensuring a consistent user experience across platforms. By understanding the differences between React.js and React Native, developers can choose the right tool for the job and deliver exceptional user experiences across web and mobile platforms.
