react-native doctor is a new command to help you out with getting started, troubleshooting and automatically fixing errors with your development environment.
- React.Suspense is a component that let you suspend, or delay, the component rendering if the components, or soon data, are imported from outside your loaded code.
- With Code Splitting, you can divide your application code into chunks and reduce the initial loading time of your application by only loading the chunk necessary for the initial render.

- While the chunks are loading suspense shows a fallback component until the chunk is ready to render.
