Use useMemo for React performance optimization when caching expensive computations, maintaining stable object references for child components, or stabilizing context provider values and effect dependencies.
To prevent unnecessary re-renders of memoized child components, use useMemo to ensure stable object and array references are passed down as props, preserving referential equality across parent renders.
The best way to optimize filtering and sorting logic is to wrap the calculations in useMemo, caching the results so they only recompute when the underlying data or search query dependencies change.
You should avoid using useMemo in React for trivial computations or when the caching overhead outweighs the performance benefit, applying a decision heuristic based on performance profiling.
Your React useEffect might run unnecessarily if object or array dependencies lack stable references, which can be resolved by wrapping those dependencies in useMemo to maintain referential equality.
