state management questions

useContext can simplify global state management by allowing components to access context values directly. However, it can lead to performance issues due to re-renders of all consumers when context values change. For complex state, consider using dedicated state management libraries.

Best practices for managing global state with Redux include organizing state into slices, using action creators and reducers for clarity, employing middleware like Redux Thunk for async actions, and normalizing state to avoid deeply nested structures.

App state in React Native can be managed using various methods. For simpler state management, you can use the Context API or React's `useState` and `useReducer` hooks. For more complex state needs, libraries like Redux or MobX offer advanced state management solutions. These libraries help you manage state across your application and keep it in sync with the UI.

JWT and session-based authentication differ primarily in how they manage user sessions. Session-based authentication requires storing session data on the server, typically in memory or a database, and uses session IDs to identify users. JWT, however, is stateless and stores all authentication information in the token itself, which is managed on the client side. While session-based authentication requires server-side storage and management, JWT simplifies scalability and reduces server load by eliminating the need for session state on the server.
