Managing component state is essential for creating interactive React applications with dynamic data, form inputs, and user interface updates. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented useState in thousands of React components including form controls, modal dialogs, and dashboard widgets. From my expertise, the most modern and efficient approach is to use the useState hook in functional components. This method provides clean syntax, better performance, and easier testing compared to class-based state management.
