React Hooks, though popular, can lead to common pitfalls when transitioning from class components, often due to differences in handling side effects and state changes. One issue is code duplication, as seen in class components with methods like `componentDidMount` and `componentDidUpdate`, which can be streamlined using the `useEffect` Hook that runs effects based on specific state changes. Overuse of `useEffect` can complicate code, as demonstrated in the TodoList example, where actions should instead be handled directly in API calls. Another concern is unnecessary re-renders caused by using `useState` for values that do not affect the UI, where `useRef` would be more efficient. A common bad practice is using `onClick` for navigation, which is better handled by `<Link />` to improve accessibility and user experience. Additionally, rewriting tests for components using Hooks should focus on user interactions rather than implementation details, ensuring tests remain stable through component refactors.
