It is implemented using react– native– pager-view on Android & iOS. It is a cross-platform Tab View component for React Native. React Native also exposes JavaScript interfaces for platform APIs, so your React Native apps can access platform features like the phone camera, or the user’s location. Thus, your application will be rendered using real mobile UI components, not webviews, and it will look and feel like any other mobile application. Then, under the hood, the React Native “bridge” invokes the native rendering APIs in or Java (for Android) and Objective-C (for iOS). React Native applications are written using a mixture of JavaScript and XML-Esque markup, known as JSX. It is based on React, Facebook’s JavaScript library for building user interfaces and it targets mobile platforms. React Native is a JavaScript framework for writing real, natively rendering mobile applications for iOS and Android.
