Anti-patterns to detect

1. Wrapping a slow component in React.memo when state can be moved down: If a component re-renders because of state it doesn't use, move that state into a smaller child component instead of memoizing. The slow component stops re-rendering without memo.
2. Wrapping in React.memo when children can be lifted up: If a parent owns state that changes frequently, extract the stateful part and pass the expensive subtree as . Children passed as props don't re-render when the parent's state changes.
