React Hooks Rules And Best Practices
React hooks are a powerful feature that allows developers to manage state and side effects in functional components. To ensure proper functionality, there are essential rules to follow: hooks must only be called at the top level of a React function and cannot be called inside loops, conditions, or nested functions. Additionally, they should only be used within functional components or custom hooks. Best practices include using the `useState` and `useEffect` hooks for state handling and side effects, respectively, grouping related state together, creating custom hooks for reusable logic, and carefully managing dependency arrays to optimize performance. Following these guidelines not only leads to cleaner, more maintainable code but also enhances the overall efficiency of React applications.
