Mobile Application
react vs react native

React has developed as a powerful and popular technology for developing Web and Mobile applications. However, there is often confusion surrounding React js vs React Native.

Both are the same entity or do they perform separate functions?

We will look at the key differences between React vs React Native, highlighting their respective capabilities, use cases, and benefits.

1. Introduction to React Js vs React Native

What is React Js?

Generally React js known as React, is a JavaScript package mostly used for creating web user interfaces.Developed and maintained by Facebook, React has gained immense popularity for its efficiency and simplicity. It helps developers to construct interactive and dynamic web applications by employing a component-based design.

What is React Native?

React Native, on the other hand, is a React Js extension that concentrates on mobile app development. It helps the developer to utilize the same codebase for both Android and IOS applications, reducing development time and effort. React Native does this by rendering native components, resulting in a highly responsive and native-like user experience.

2. Underlying Technologies

React Js Technology Stack

React js is based on JavaScript and uses a Virtual DOM (Document Object Model) to efficiently update and render UI components.
It can be combined with a variety of tools and libraries, including Redux for state management that helps to keep track of data in a React application, Axios for A library for making HTTP requests to APIs., and React Router- A library for managing navigation in a React application.

React Native Technology Stack

React Native, on the other hand, is a React.js extension that concentrates on mobile app development. It helps the developer to utilize the same codebase for both Android and iOS applications, reducing development time and effort. React Native does this by rendering native components, resulting in a highly responsive and native-like user experience.

3. Development Environment

React Js Development Environment

Developers working with React.js can utilize popular code editors like Visual Studio Code or WebStorm. Setting up a development environment for React.js involves installing Node.js and npm (Node Package Manager). React development can be done in any modern web browser.

React Native Development Environment

React Native development requires the installation of additional tools, for iOS developmentXcode” and Android Studio for Android development. While it may have a steeper initial setup, it offers a streamlined development experience for mobile apps.

4. User Interface

React Js for Web UI

React.js is primarily used for creating web-based user interfaces. Developers can ease their tasks using open-source frameworks or HTML and CSS to build creative and responsive web applications. React components are reusable and can be combined to create complex UIs.

React Native for Mobile UI

React Native is an expert in mobile user interfaces. It renders using native components, resulting in a UI that closely matches that of native apps. This structure results gives a smoother user experience on mobile devices.

5. Code Reusability

React Js Code Reusability

React.js promotes code reusability by allowing the creation of reusable components. However, the codebase itself is not directly reusable for mobile app development.

React Native Code Reusability

React Native takes code reusability to the next level. Developers can share a significant piece of their codebase between Android and iOS platforms to reduce duplication of effort and maintenance.

6. Comparing Performance

React Js Performance

React.js offers excellent performance for web applications. It optimizes rendering through the Virtual DOM, ensuring efficient updates even for complex UIs.

React Native Performance

React Native delivers impressive performance on mobile devices. By using native components, it provides a highly responsive and native-like experience to users.

7. Native Device Features

React Js and Native Device Features

React.js is primarily designed for web applications and does not offer direct access to native device features like GPS or camera.

React Native and Native Device Features

React Native excels in accessing native device features through native modules and third-party libraries, making it suitable for building feature-rich mobile apps.

8. Community and Ecosystem

React Js Community and Ecosystem

React.js has a vast and active community. React has a large ecosystem of web development frameworks and tools, making it an excellent solution for building web-based projects.

React Native Community and Ecosystem

React Native also has a thriving community, with a growing ecosystem of plugins and libraries for mobile development. This support network ensures developers have the resources to overcome challenges.

9. Learning Curve

Learning React Js

React.js is easy to learn, especially for those who are familiar with JavaScript and HTML. The component-based structure simplifies UI development.

Learning React Native

Learning React Native may require a bit more effort due to mobile-specific concepts and native modules. However, it can be an efficient choice for developers already proficient in React.js.

10. Use Cases

Typical Use Cases for React Js

  • Building dynamic web applications
  • Single-page applications (SPAs)
  • E-commerce websites
  • Content management systems (CMS)

Typical Use Cases for React Native

  • Cross-platform mobile app development
  • Rapid prototyping of mobile apps
  • Apps requiring access to native device features.
  • Maintaining a single codebase for both Android and iOS apps

11. Pros and Cons

Pros and Cons of React Js


  • Fast rendering through Virtual DOM
  • A rich ecosystem of libraries
  • The easy learning curve for web developers


  • Limited to web development
  • Less access to native device features

Pros and Cons of React Native


  • Cross-platform development with a single codebase
  • Native-like user experience
  • Access to native device features


  • Requires platform-specific adjustments
  • The initial setup can be complex

12. Integration with Other Technologies

Integrating React Js with Other Technologies

React.js can be seamlessly integrated with various technologies such as Redux for state management, GraphQL for efficient data fetching, and Jest for testing.

Integrating React Native with Other Technologies

React Native supports integration with native modules and third-party libraries for accessing device features. It can also work with technologies like Redux and Apollo Client for managing state and data.

13. Development Time and Costs

Development Time with React Js

Developing web applications with React.js is often faster due to the simplicity of the framework. However, it may require additional effort for mobile app development.

Development Time with React Native

React Native can significantly reduce development time and costs for mobile app projects by enabling code reuse between platforms.

14. Choosing Between React Js and React Native

Factors to Consider

When deciding between React.js and React Native, consider the following factors:

  • Project requirements (web or mobile)
  • Access to native device features
  • Development team expertise
  • Budget and timeline constraints

Making the Right Choice

The choice between React js vs React Native ultimately depends on your specific project needs. Both technologies have well defined advantages and choosing the appropriate one can help your application succeed.

15. Conclusion

Finally, React vs React Native are both great technologies for developing web and mobile applications. React js is great for web UI development while React Native is the get-to go choice for cross-platform mobile app development. Understanding the contrasts and strengths of various technologies is critical for making informed development decisions.
