Difference Between React JS and React Native

Difference Between React JS and React Native
May 4, 2022 No Comments


React has emerged as a powerhouse. Its versatility and efficiency have made it a favorite among developers worldwide. However, the React ecosystem isn’t confined to a single platform; it extends its reach to both web and mobile development through React JS and React Native, respectively. While both frameworks share similarities, they cater to distinct platforms and serve different purposes. In this blog post, we delve into the intricacies of React JS and React Native, highlighting their differences and exploring when to use each.

Understanding React JS:

React JS, often referred to simply as React, is a JavaScript library developed by Facebook. It’s primarily used for building user interfaces (UIs) for web applications. React follows a component-based architecture, where UIs are broken down into reusable components, making the development process more modular and efficient. React utilizes a virtual DOM (Document Object Model), which enhances performance by minimizing DOM manipulation. With its declarative syntax and efficient rendering, React simplifies the process of creating dynamic and interactive web applications.

Key Features of React JS:

  1. Component-Based Architecture: React applications are composed of reusable components, promoting code reusability and maintainability.
  2. Virtual DOM: React’s virtual DOM efficiently updates and renders UI components, enhancing performance.
  3. JSX: JSX, a syntax extension for JavaScript, allows developers to write HTML-like code within JavaScript, making the creation of UI components more intuitive.
  4. One-Way Data Binding: React follows a unidirectional data flow, ensuring that data changes are propagated downwards from parent to child components, simplifying data management.
  5. Rich Ecosystem: React boasts a vast ecosystem of libraries, tools, and community support, facilitating rapid development and scalability.

Understanding React Native:

React Native, an extension of React is a framework for building native mobile applications using JavaScript and React. Developed by Facebook, React Native enables developers to create cross-platform mobile apps that look and feel like native applications. Unlike traditional hybrid frameworks, React Native leverages native components, resulting in superior performance and a native user experience. By sharing a single codebase across multiple platforms, React Native streamlines the development process and reduces time-to-market, making it an ideal choice for mobile app development.

Key Features of React Native:

  1. Cross-Platform Development: React Native allows developers to build mobile apps for multiple platforms, including iOS and Android, using a single codebase, saving time and resources.
  2. Native Components: React Native utilizes native UI components, ensuring high performance and a native look and feel across different platforms.
  3. Hot Reloading: React Native supports hot reloading, enabling developers to instantly preview changes made to the code without recompiling the entire application, speeding up the development cycle.
  4. Access to Native APIs: React Native provides native device APIs through JavaScript, allowing developers to integrate device-specific features seamlessly into their applications.
  5. Community and Ecosystem: Similar to React JS, React Native has a vibrant community and extensive ecosystem, offering a plethora of libraries, plugins, and tools to enhance development productivity.

Differences Between React JS and React Native:

  1. Platform: React JS is used for web development, whereas React Native is used for mobile app development.
  2. Rendering: React JS renders components to the browser’s DOM, while React Native renders components to native UI elements.
  3. Styling: React JS uses CSS for styling web applications, whereas React Native uses a combination of JavaScript and StyleSheet API for styling mobile apps.
  4. Components: While React JS and React Native follow a component-based architecture, the components are platform-specific. React JS components are tailored for web browsers, whereas React Native components are designed for mobile devices.
  5. Performance: React JS offers excellent performance for web applications, but React Native provides superior performance for mobile apps by leveraging native components.


In conclusion, React JS and React Native are both powerful frameworks for building dynamic and interactive applications, but they cater to different platforms and serve distinct purposes. React JS excels in web development, offering a modular and efficient approach to building UIs for web applications. On the other hand, React Native shines in mobile app development, enabling developers to create cross-platform apps with native-like performance and user experience. Understanding the differences between React JS and React Native is crucial for choosing the right framework based on the project requirements and target platform. Whether it’s web development with React JS or mobile app development with React Native, the React ecosystem continues to revolutionize how we build applications in the digital age.
