Problem Statement
What configuration options does configureStore accept and when would you customize them?
Explanation
configureStore accepts reducer (required, can be a single reducer or object of slices), middleware (to customize or add middleware, defaults to getDefaultMiddleware), devTools (to configure Redux DevTools, enabled by default in development), preloadedState (for SSR or rehydration), and enhancers (for advanced Redux setup). You would customize middleware to add custom middleware like logging or analytics, disable certain checks in production for performance, configure DevTools options for debugging needs, or add enhancers for features like persistence. Most applications can use the defaults and only need to pass the reducer configuration.
