Getting started with React Native and Expo SDK

Expo is an open-source platform that streamlines the development of cross-platform iOS and Android mobile apps by leveraging JavaScript to access device system features through its SDK, which includes a variety of native libraries. The platform requires Node.js for installation and utilizes Expo CLI for app testing and development. Expo supports various built-in libraries for common app functions like authentication, splash screens, localization, and secure storage, as well as features like push notifications and audio control. While Expo simplifies app development, it has limitations such as restricted background code execution and being confined to the APIs supported by the Expo SDK. Recent updates have enhanced its developer tools, error management, and TypeScript integration. Despite some constraints, Expo remains a valuable tool due to its extensive support for Android and iOS APIs, making it suitable for most app development needs without the need for additional native features.
