Answer
Props are read-only inputs passed from parent components, while state is internal mutable data managed by the component.
Quick Answer
Props are read-only inputs passed from parent to child — the parent controls them. State is internal data owned and managed by the component itself. Props flow down; state triggers re-renders when it changes. A component can't modify its own props, but it can update its own state with a setter function.
