One simple trick to optimize React re-renders

Kent C. Dodds:

If you’re experiencing React performance issues, try this:

  1. “Lift” the expensive component to a parent where it will be rendered less often.
  2. Then pass the expensive component down as a prop.

You may find doing so solves your performance problem without needing to spread React.memo all over you codebase like a giant intrusive band-aid 🤕😉

Nice one!
