Summary

Functional components in React can maintain their state through Hooks like useState, eliminating the need for class-based components, but they still require careful handling to avoid misusing the state. A common mistake is directly mutating state, which is against React's immutability principles and can prevent UI updates. Proper state management involves using the setState function from useState to ensure changes trigger re-renders. It's also recommended to use hooks at the top level of components and avoid using them in class components or regular JavaScript functions, as this can lead to errors. Moreover, while useState is suitable for simple state management, larger applications benefit from using state management libraries like Redux or the Context API to handle more complex requirements, preventing issues like "Prop Drilling" and ensuring better scalability and maintainability.
