React vs React Native: When to Use Which?

React is a widely embraced library for creating user interfaces, commonly used in both web and mobile development. It has gained popularity for its adaptability and user-friendliness, making it a valuable skill in the IT job market. However, the presence of different versions of React, such as ReactJS and React Native, can perplex newcomers, making it challenging to discern when to employ each. This guide aims to furnish a comprehensive overview of both technologies and assist you in making an informed decision about which one suits your project best.

1. What is ReactJS?

ReactJS is a JavaScript library designed for crafting user interfaces in web applications. Developed and maintained by Facebook, it has become one of the most prevalent and widely used JavaScript libraries. ReactJS empowers developers to construct dynamic and scalable user interfaces for web applications by segmenting the interface into small, reusable components. These components can be effortlessly managed and updated independently, simplifying the development and maintenance of intricate user interfaces.

ReactJS employs a virtual DOM (Document Object Model), a lightweight representation of the actual DOM, to efficiently update the user interface. This mechanism calculates and applies changes only to the parts of the interface that have been altered, leading to faster and more efficient updates compared to traditional approaches.

Prominent companies such as Facebook, Instagram, Netflix, Airbnb, and Walmart rely on ReactJS for their web applications, underscoring its market dominance and continued growth in popularity.

2. When to Use ReactJS?

ReactJS is ideally suited for web development projects that necessitate dynamic and interactive user interfaces built on JavaScript. Common scenarios for using ReactJS include:

a. Single-Page Applications (SPAs):

ReactJS excels in constructing SPAs, where the entire UI can update dynamically without necessitating a full page refresh.

b. Complex Web Interfaces:

It simplifies the creation of complex user interfaces by breaking them down into smaller, reusable components, streamlining development and promoting maintainable code.

c. Large-Scale Web Applications:

ReactJS has been tested at scale and is utilized by numerous large companies for their web applications, demonstrating its ability to handle complex use cases.

d. Responsive Web Design:

Developers can use ReactJS to build responsive and adaptable user interfaces that seamlessly adapt to various devices, from desktop computers to mobile phones.

ReactJS boasts a robust community of developers and a well-established ecosystem of tools and resources, rendering it a dependable and well-supported choice for web development projects.

3. Benefits and Limitations of ReactJS

Benefits of Using ReactJS Over Traditional Web Development:
  • Improved Performance: ReactJS’s virtual DOM leads to faster and more efficient UI updates, enhancing the overall user experience and performance.
  • Reusable Components: ReactJS encourages the decomposition of UIs into reusable components, simplifying maintenance and scalability.
  • Cross-Browser Compatibility: ReactJS functions seamlessly on major web browsers, ensuring cross-browser compatibility for web development.
  • Large and Active Community: A vast and active developer community supports ReactJS, facilitating access to resources and support.
  • Strong Ecosystem of Tools and Resources: ReactJS enjoys a well-established ecosystem comprising libraries, plugins, and resources that simplify development and enhance code quality.
Disadvantages of Using ReactJS Compared to Traditional Web Development:
  • Steep Learning Curve: ReactJS can be challenging to learn, especially for developers new to JavaScript or web development.
  • Complex Codebase: ReactJS may lead to a more intricate codebase due to its reliance on components and the virtual DOM.
  • Dependence on Other Technologies: ReactJS relies on other technologies like JavaScript, the DOM, and TypeScript, which can limit flexibility and suitability for certain use cases.
  • JSX Limitations: ReactJS employs JSX, a powerful but potentially complex JavaScript syntax extension for writing components.
  • Browser Compatibility: ReactJS applications may not function well on older or less modern browsers, as they rely on contemporary web technologies.
4. What is React Native?

React Native, on the other hand, is a framework for building mobile applications. Developed by Facebook, it enables the creation of mobile apps for multiple platforms, including iOS and Android, using a single codebase. React Native aims to provide a native look and feel while sharing as much code as possible between different platforms.

5. When to Use React Native?

React Native is the preferred choice when developing mobile applications, particularly for scenarios such as:

  • Building a Simple Mobile Application: React Native is ideal for creating mobile apps, offering a single codebase that works on both iOS and Android.
  • Building a Cross-Platform Application: It excels in situations where cross-platform compatibility is crucial, with potential for enhanced cross-platform performance.
  • High-Performance Needs: React Native can deliver excellent performance and is often chosen for applications demanding high speed and responsiveness.
  • Frequent Updates and Iterations: It supports a fast development cycle, making it suitable for applications requiring frequent updates and changes.
  • Access to Native Features: When your application requires access to native device features, React Native provides seamless integration through native modules.
6. Difference between ReactJS and React Native

The main distinction between ReactJS and React Native lies in their respective domains of application:

  • ReactJS is best suited for web development, focusing on creating dynamic web user interfaces.
  • React Native specializes in mobile application development, allowing you to build native mobile apps for iOS and Android with a shared codebase.


The choice between ReactJS and React Native depends on your project’s specific requirements. ReactJS excels in web development, while React Native is the preferred option for mobile app development, especially when targeting multiple platforms. Consider the unique features and demands of your project to make an informed decision.
