Learn to use form state hook with an optional control to isolate rerendering and manage the is submitting state during form submissions.

Learn to retrieve individual and nested field states with get field state in use form, control subscriptions for real-time values, and optimize performance by selective subscriptions and component placement.

Watch form control values with the watch method to subscribe to single or multiple controls, see real-time updates, and use useEffect for actions and unsubscribe when unmounting.

Learn to use the useWatch hook to isolate rerendering by subscribing to individual form input changes within a form context, improving performance without triggering parent renders.

Explore how to use get values and set value in React Hook Form to retrieve and update form fields, with examples of single, multiple, and all controls.
