This document discusses the various navigation options available in React Native and provides recommendations on which to use. It begins with a brief history of the different navigators, including NavigatorIOS, Navigator, Ex-Navigation, and NavigationExperimental. It identifies React Navigation and React Native Navigation as the primary options today. React Navigation is recommended for apps created with Expo or Create React Native App, while React Native Navigation may be better for more complex native apps due to its use of native navigators. Both have pros and cons around performance, ease of use, and customization.
