An Introduction to React Native: Building Real Native Mobile Apps

TLDRReact Native is a powerful library for building real native mobile apps for iOS and Android. It leverages the React ecosystem and provides a collection of special components that are compiled into native UI elements. React Native allows developers to write code once and deploy it on multiple platforms. It works by running JavaScript code on a separate thread in the native app and communicating with the underlying platform through a translation bridge. Expo CLI is a recommended tool for getting started with React Native development.
