React Native vs. React – Deciphering the Differences

Date: 04.30.24

React and React Native have revolutionized how developers build user interfaces and mobile applications. Developed by Facebook, these frameworks share a common foundation in JavaScript and a component-based architecture. However, they diverge in their target platforms, rendering mechanisms, styling approaches, access to native APIs, and performance optimizations. In this article, we’ll explore the key differences between React Native and React, shedding light on their unique strengths and ideal use cases.

Understanding React and React Native


React, also known as React.js or ReactJS, is a JavaScript library for building user interfaces for web applications. It utilizes a declarative and component-based approach, allowing developers to create reusable UI components that efficiently update in response to changes in the application state.


In contrast, React Native is a framework for building cross-platform mobile applications using JavaScript and React principles. Unlike traditional mobile development frameworks, React Native leverages native components, enabling developers to create truly native user experiences for both iOS and Android platforms. React Native bridges the gap between web and mobile development by allowing developers to write code once and deploy it across multiple platforms.


Differences between React and React Native

React is a JavaScript library and React Native is a robust framework; both are equipped with unique strengths and advantages tailored to distinct development needs. Developers must grasp the disparities between these tools to make informed decisions that align with project demands. Let’s delve into the major differences between these two:

Platform Targeting

  • React’s primary focus lies in web development, where it thrives within the browser environment, catering to the diverse landscape of web platforms and browsers. By harnessing the power of JavaScript, React efficiently renders user interfaces, delivering dynamic and interactive experiences across desktop and mobile browsers alike.


  • In contrast, React Native emerges as a specialized framework tailored specifically for mobile app development. It empowers developers to harness the capabilities of iOS and Android platforms, allowing them to craft truly native mobile applications. With React Native, developers can leverage platform-specific features and functionalities to deliver seamless user experiences that align closely with the expectations of mobile users.


Component Rendering

  • React’s rendering mechanism revolves around the utilization of HTML and CSS to construct the user interface components. Through its virtual representation of the Document Object Model (DOM), React efficiently manages component updates and re-renders, optimizing performance by minimizing unnecessary manipulations of the actual DOM.
  • On the other hand, React Native transcends the boundaries of web rendering by translating React components into native UI elements. By directly interfacing with the native rendering engines of iOS and Android, React Native ensures that the resulting user interfaces maintain the look, feel, and performance characteristics native to each platform. This approach imbues React Native applications with a level of responsiveness and fluidity that closely resembles that of traditional native applications.



  • Styling in React primarily revolves around the use of Cascading Style Sheets (CSS), offering developers a familiar and powerful toolset for defining the visual appearance of their user interface components. Additionally, React extends support for CSS-in-JS solutions, enabling developers to encapsulate styles within their components for improved modularity and maintainability.
  • In the realm of React Native, styling takes on a slightly different approach. While developers can still utilize CSS-like syntax through the “StyleSheet” API, React Native introduces platform-specific styling options to ensure consistency and adherence to platform design guidelines. By leveraging platform-specific style properties and components, React Native applications seamlessly blend with the native look and feel of iOS and Android, enhancing user engagement and usability.


Access to Native APIs

  • One of the hallmark features of React Native is its direct access to native APIs, empowering developers to harness the full spectrum of device-specific functionalities. Whether it’s accessing the device camera, retrieving geolocation data, or sending push notifications, React Native provides a seamless bridge between JavaScript code and native platform capabilities.
  • In contrast, React, primarily designed for web development, lacks direct access to native APIs. To interact with device features such as camera access or geolocation, React developers often rely on third-party libraries or wrappers that provide JavaScript interfaces to native functionalities. While these solutions offer a degree of interoperability, they may introduce additional complexity and dependencies to the development process.



  • Performance optimization lies at the core of both React and React Native, albeit in different contexts. React excels in optimizing rendering performance within web browsers by efficiently managing the Virtual DOM. By minimizing unnecessary DOM manipulations and leveraging reconciliation algorithms, React ensures fast and responsive user interfaces, even in the face of complex application logic.
  • React Native takes a different approach to performance optimization, prioritizing near-native performance on mobile devices. By compiling React components into native code, React Native bypasses the performance limitations inherent in web-based rendering, resulting in smooth animations, responsive interactions, and reduced latency. This native compilation process ensures that React Native applications deliver a level of performance and fluidity that rivals traditional native applications, enhancing user satisfaction and engagement.



React and React Native offer powerful tools for building user interfaces and mobile applications, each with its own set of strengths and advantages. Understanding the differences between these frameworks is crucial for developers to choose the right tool for their specific project requirements. 

Whether it’s web development with React or mobile app development with React Native, both frameworks empower developers to create high-quality, performance t applications across a variety of platforms.
