How React Controlled Components Give Developers Full Control Over Form Data

React handles form inputs differently from standard HTML, where submitting a form typically reloads the page and clears all entered data. In React, developers use controlled components by binding input fields to state variables via the value and onChange props, creating a single source of truth for each field's data. Uncontrolled inputs lack this state management, meaning their values are not tracked or managed by React. The onChange handler updates the state on every keystroke, keeping the displayed value in sync with the component's state. For forms with multiple fields, developers can consolidate multiple useState calls into a single object-based state for cleaner, more maintainable code.
