To avoid unnecessary state and useEffect in React components, favor derived state over useState for values calculated from props. Use external libraries like TanStack Query for data fetching instead of managing side effects manually.

The best way to structure modern React components is keeping them flat with clear naming and proper prop typing. This ensures clarity, correctness, and maintainability while avoiding inefficient rendering patterns and complex nested hierarchies.

You should use useMemo sparingly for performance optimization in React. Apply it only for expensive calculations to prevent unnecessary re-renders, rather than wrapping every derived value, which can introduce overhead and reduce overall component performance.

Your React component has redundant state because values are stored in useState instead of being derived during render. Refactor by removing useState for calculated values, eliminating unnecessary useEffect calls, and deriving state directly from existing props.

Yes, you can use TanStack Query instead of useEffect for data fetching in React. It handles caching, synchronization, and state management externally, eliminating the need for manual side effect management and reducing component complexity.

Deriving state during render eliminates the need for useEffect in React components when values depend purely on props or existing state. Calculate values directly in the component body to avoid unnecessary state management and minimize side effects.
