Problem Statement
Why should Redux state be serializable?
Explanation
Redux state should be serializable (convertible to JSON) to enable features like persisting state to localStorage, time-travel debugging in Redux DevTools, server-side rendering with state hydration, and sending state across network boundaries. Non-serializable values like functions, Promises, class instances, or Dates can break these features and make debugging harder. RTK includes checks in development that warn you about non-serializable values, though you can configure exceptions for specific paths if absolutely necessary.
