React patterns to avoid common pitfalls in local state management

The text delves into the intricacies of state management in React applications, focusing primarily on local state management and common patterns to avoid pitfalls. It covers various types of states, such as fetching data from APIs, local states needed by nearby components, and global states used across the application. The article emphasizes the importance of understanding how state works in React, particularly through the useState Hook, which is a fundamental tool for managing component states. It highlights common pitfalls like the stale state problem and accessing states synchronously, providing solutions like using updater functions and the useEffect Hook. Additionally, it explores more efficient state management approaches for complex scenarios, suggesting the use of useReducer to maintain cleaner code and separation of concerns. The text also addresses the challenge of accessing the latest state from asynchronous callbacks and recommends using the useRef Hook for mutable data that doesn't trigger re-renders. The discussion concludes with advice on adhering to the rules of Hooks to avoid common pitfalls in React state management.
