✓ 应当这么做
- ✓ Keep components pure during render; move side effects into effects or event handlers
- ✓ Lift state only as high as the closest common consumer needs it
- ✓ Give every list a stable key derived from the item identity, never from the array index when order can change
✕ 常见反模式
- ✕ Deriving state in useEffect when a plain computed value would do
- ✕ Passing fresh object or function literals into memoized children every render
- ✕ Mixing data fetching concerns directly into presentational leaf components
◎ 交付前验证
- ◎ React DevTools profiler shows no render loops after the change
- ◎ Strict Mode double-invocation does not duplicate side effects
- ◎ Server and client render output match (no hydration mismatch warnings)
