Answer

  1. Use React.memo to prevent unnecessary re-renders of functional components.
  2. Implement shouldComponentUpdate in class components to control when updates occur.
  3. Use React.lazy and Suspense for code-splitting, loading components only when needed.
  4. Optimize the use of key props in lists to help React identify which items have changed.
  5. Limit the size of the component tree being rendered in a single pass.
