Bit #36

Heuristics for optimizing React’s performance:

  1. If you can solve the problem by altering component hierarchy or state, prioritize that!
  2. Memoization is a solid strategy only if the cost of checking pays for itself with the time you save rendering.
  3. Use Lazy/Suspense API to progressively load components.
  4. Use the Transition API (useTransition / useDeferredValue) when you’re really in a pickle (e.g something is computationally expensive, but not running it is not a choice).
