You can reuse stateful React logic by extracting repeated component behavior into custom hooks. This encapsulates shared state and side effects into functions starting with use, allowing multiple components to share the same logic cleanly.

Refactoring class-based React components to hooks involves replacing lifecycle methods and wrapper patterns with useState and useEffect. This approach provides fallback guidance for class-to-hooks migration, reducing wrapper complexity through cleaner functional composition.

Managing useEffect dependencies requires correct use of dependency arrays and adherence to the Rules of Hooks. Proper dependency tracking prevents subtle side-effect bugs by ensuring effects run only when specified state or props change.

You need custom hooks for React form handling and subscriptions when shared stateful behavior is duplicated across components. Encapsulating these UI features into custom hooks replaces wrapper patterns and ensures reusable, safe side-effect execution.

Custom hooks replace higher-order components and render props by composing stateful behavior directly within functional components. This reduces wrapper complexity and eliminates nested component hierarchies previously needed for sharing logic.

Custom hooks are limited by the Rules of Hooks, requiring you to call hooks only at the top level of functional components. You must ensure correct useState and useEffect usage to avoid breaking state management and causing unpredictable rendering.
