What is react-native?

• React-Native is a programming language that is used to create a mobile application which works on both platforms Android and IOS.

• It’s based on React, Facebook’s JavaScript library for building user interfaces, but instead of targeting the browser, it targets mobile platforms.

• React Native applications are written using a mixture of JavaScript and XML-esque markup, known as JSX. Then, under the hood, the React Native “bridge” invokes the native rendering APIs in Objective-C (for iOS) or Java (for Android). Thus, your application will render using real mobile UI components, not webview, and will look and feel like any other mobile application.

Why use react-native?

1. Cross-Platform
   One of the most significant advantages of React Native is that you can develop an application for both Android and IOS ecosystems simultaneously by writing the same code with just a few modifications for each platform.
2. JavaScript
   There is no need to know the languages used for platform-specific application development, as React Native uses only JavaScript, probably the most popular programming language right now, for the development of mobile applications.
3. Performance
   React Native enables speedy development of mobile applications since a similar code is used for applications for both platforms. It also facilitates a hot reloading feature that makes sure that small changes done to the application are immediately visible to the developer.
4. Large Developers’ Community
   A huge developers’ community ensures that all the queries are resolved in time, and therefore, adequate support is available for the React Native framework.
5. It Keeps Getting Better
   The community, as mentioned above, also keeps updating React Native with new functionalities and making sure that bugs do not occur.
6. Used by Many Companies
   Though the framework is relatively new, many companies have already migrated the applications to this framework. Additional companies are looking to use the framework to speed up the process of development and maintenance.
7. Excellent Career Opportunities
   React Native has become very popular lately due to advantages like cross-compatibility. Consequently, this popularity has led to high demand for React Native developers.

Conclusion

• React Native is a JavaScript framework that is used to develop mobile applications for iOS and Android. It lets you build cross-compatible mobile applications using only JavaScript, and you don’t have to worry about learning platform-specific application development languages such as Kotlin for Android or Swift for iOS.
