Props are read-only data passed from a parent component, while state is mutable data controlled by the component itself.
Props are used to pass data from a parent component to a child component.
Props are immutable and cannot be modified by the child component.
State is used to manage mutable data within a component.
State can be modified using the setState() method.
Changes in props trigger re-rendering of the component, while changes in state trigger component updates.
