What Is The Difference Between ReactJS and React Native?

Overview – 

ReactJS is a JavaScript library used to build single-page web applications. React Native is a ReactJS-based framework used to design mobile apps. With ReactJS, you can create the skeleton of the applications, React Native allows you to create native mobile apps with its reusable components. Both of them are industry favorites and they are used by many for mobile and web applications.

What is ReactJS?

ReactJS is an open-source JavaScript library developed and backed by Facebook in 2011. You can hire ReactJS developers for creating single-page web applications. For developing front-end web and mobile apps, it is one of the most preferred frameworks.

Web and mobile applications are intuitive and adaptive. They can be developed quickly. The designing process can also be automated. ReactJS allows developers to integrate libraries and plugins with existing code. The apps developed with ReactJS are scalable, simple, and fast. It is a perfect choice for single-page apps and static websites.

What is React Native?

React Native is a mobile development library developed by Facebook. Just like ReactJS, React Native is also JavaScript-based and open-source. For mobile needs, the demand for React Native is getting higher each day. With a single codebase, you can develop apps for multiple platforms.

Across iOS and Android, React web development lets you build apps that render natively. With a single framework, React Native developers can build apps for both iOS and Android through React Native.

Differences between ReactJS and React Native

Here are some of the key differences between ReactJS and React Native.


Since ReactJS is a JavaScript library, you only need to integrate the library into the HTML page in the script tag. On the other hand, you will need a development environment like Android Studio or Xcode for Android and iOS respectively.


ReactJS can help you with great UI since it executes itself on the client-side while being rendered on the server-side. This improves efficiency right from the elements like buttons to elements like dropdowns. With React Native, the components are directly compiled into native code. It is possible to create great-looking and functioning apps with React Native.


To be a master at ReactJS, you need to learn and understand JavaScript. React Native, on the other hand, is not a pure JavaScript framework. It is a combination of C++, Objective-C++, Objective-C, and Java. A developer will need to have a good command of these languages to develop an app with React Native.


ReactJS has been created considering Search Engine Optimization (SEO) in mind. With ReactJS, it renders on the user’s server using Node. React Native is to develop a mobile UI. The apps with React Native are also smooth and fast.


ReactJS renders HTML components like <p>, <h2>, etc. The markup is written in JavaScript and it doesn’t distinguish between markups and logic. React does not render with HTML-like components. Because of this difference between ReactJS and React Native, the latter is not preferred for web development. With React, developers can develop mobile apps, or apps for smartwatches, TV, AR, etc.


ReactJS has two types of components: Functional and Class. Class components are known to have more features, however, the functional components offer better code readability. React Native has both components and modules. You can find specific components in the UI explorer for React Native. It also allows developers to create and reuse customized components.


ReactJS developers have the access to a react-router library that offers click-event navigation. On the other hand, React Native does not allow the use of a react-router but a unique library navigator. This React Native Navigation helps with accurate native platform navigation across operating systems.


With React, the data is stored and managed in local storage. The data in the local storage does not expire and it will persist even when the browser is closed. Whereas, React Native uses AsyncStorage which allows local data storage in its libraries. In Android, RocksDB and SQLite are used. With iOS, AsyncStorage is backed by native code, storing small values in a particular format and large values in individual files.

Advantages: ReactJS vs React Native


  • Anyone with an understanding of JavaScript can learn ReactJS easily. There are a bunch of guides and tutorials available online, as well.
  • ReactJS also comes with reusable components that offer their own logic and rendering. This translates to faster web development.
  • The virtual DOM ensures higher performance with a lightweight copy of the real DOM updated. It helps in the efficiency and reusability of ReactJS.

React Native 

  • React Native is an easy-to-implement library. It offers the same app development as JavaScript but with better flexibility. It also improves the skills of developers working on it.
  • React Native also allows developers to develop cross-platform apps that can be deployed on both Android and iOS.
  • React Native also demands less debugging and optimization, less testing, and enhancements.

Disadvantages: ReactJS and React Native


  • Many developers think JSX documentation is difficult to learn, the extension used by ReactJS.
  • There are frequent changes in React Library that can also be a cause of concern for many developers.
  • There are few native modules in ReactJS, even though it offers third-party modules and plugins.

React Native 

  • The dependency on third-party libraries decreases the development speed and creating a custom module creates three individual codebases of RN, iOS, and Android.
  • The React Native developers also suffer from the slow application load time. The JavaScript thread takes time to deploy, which makes the loading time an issue for React Native.

ReactJS and React Native: Which Is Better?

The use of both technologies is very different. It completely depends on what you want to create. On one hand, you can use React for building feature-rich web applications that are fast and reliable. React Native, on the other hand, is used for cross-platform app development. They are both widely used to create modern and scalable apps.

What is Redux?

Redux is a framework for state  management. It is mostly used with ReactJS based applications. Redux has a central store for managing states and it can be used throughout the application.

What is Redux Middleware?

Redux middleware are used to intercept an action before it reaches to the reducer. These middleware are used for logging, error reporting, asynchronous communications etc. Redux -Saga and Redux Thunk s  are the most popular middleware.
