Quick Summary: React and React Native are two of the most common platforms for making modern web apps, although they do differ from one another. React is for making web interfaces that change and interact with users, whereas React Native is for making mobile apps that use the same JavaScript code as React. This blog talks about the differences, pros, and cons of each one to help you pick the best one for your project. Find out how each technology can affect the next digital product you make.
Introduction
Have you ever experienced some websites and apps looking the same on a browser and a smartphone?
Behind that smooth experience, there are two powerful technologies – React and React Native. Both were created by Meta and share the same basic philosophy, but serve completely different purposes. ReactJS powers dynamic and responsive web applications, while React Native brings those same concepts to life on mobile devices.
Choosing between React and React Native has become an important decision for developers and global businesses. React dominates web development with over 11 million websites globally, while React Native is the leader in cross-platform mobile development with 42% market share in the mobile app development sector.
What is React.js?
React.js Web Development, often referred to as React, is a part of the JavaScript library used to create interactive user interfaces, especially for single-page web applications. The library allows web developers to create reusable UI components that efficiently update and present data without refreshing the page. Its declarative structure makes code predictable and easier to debug.
React.JS Purpose
The main purpose of React.js is to simplify frontend development along with the process of building scalable, high-performance web applications. It efficiently manages the view layer of a web application, ensuring a smooth and responsive user experience.
React.JS Output
React web applications are compiled to standard web technologies – HTML, CSS, and JavaScript that run in web browsers. The library renders components of the Document Object Model (DOM), creating dynamic web pages that can respond to user interactions and data changes in real time. React’s virtual DOM implementation results in faster updates and improved application speed.
React.JS Components
React is completely component-driven. Each component encapsulates its own logic, design, and state, making it easy to reuse and maintain. This modular architecture supports cleaner code organization and increases collaboration across teams.
React.JS Platform
React.js is completely web-focused. It is ideal for developing applications that run in the browser, such as dashboards, social platforms, or ecommerce interfaces. With the Next.js framework, this can also be extended to server-side rendering and static site generation.
What is React Native?
React Native is a framework that allows developers to create mobile applications using JavaScript and React’s component-based architecture. Instead of rendering web components, it translates them into native UI elements, providing the same performance and experience as traditional native apps built in Swift, Java or Kotlin.
React Native Purpose
React Native aims to bridge the gap between web and mobile development by allowing code reusability across all platforms. This enables developers to use one codebase for both iOS and Android, significantly reducing development time and effort.
React Native Output
The framework compiles native code, creating true mobile applications rather than web views. This ensures smooth animations, faster load times, and a consistent user experience across all devices.
React Native Component
React Native uses native components instead of HTML elements. Elements like <View>, <Text>, and <Image> replace traditional web tags, interacting directly with the native API. This approach gives developers full access to device features like cameras, sensors, and GPS.
React Native Platform
React Native targets mobile platforms, specifically iOS and Android. However, through extensions like React Native for Windows and macOS, developers can also expand to desktop environments.
Difference between React Native and React.JS
| Aspect | React.js | React Native |
|---|---|---|
| Target Platform | Web browsers (desktop & mobile web) | Native mobile apps (iOS & Android) |
| Rendering | Renders to DOM | Renders to native components |
| Styling | CSS, CSS-in-JS, styled-components | StyleSheet API (CSS-like syntax) |
| Navigation | React Router, browser-based routing | React Navigation, native navigation |
| Development Tools | Browser DevTools, React DevTools | Metro bundler, native debugging tools |
| Deployment | Web servers, CDNs | App stores (Apple App Store, Google Play) |
| Performance | Optimized for web browsers | Near-native mobile performance |
| Code Reusability | Web-specific components | Cross-platform mobile components |
| Learning Curve | Web development knowledge required | Mobile development concepts needed |
