Answer

Memoization is an optimization technique that stores results of expensive function calls and returns the cached result when the same inputs occur again. In React, you can use:

  • React.memo to prevent unnecessary re-renders of functional components.
  • useMemo to memoize computation results based on dependencies. Benefits include:
  • Improved performance by minimizing rendering logic for unchanged data.
  • Better user experience with faster interactions. However, excessive use can lead to complexity and memory overhead if not managed properly.
