Legend
useState is the fundamental hook for managing local state in functional components. It allows you to preserve values between renders and update them in response to user input, API calls, or internal logic. It triggers a re-render when the state changes, ensuring your UI reflects the current state. In most cases useState tracks changing values inside a component.
