Figure 8.3: Common ancestor component holds state with props and event propagation

To change the state, a component needs to emit an event up to the component holding state (the shared ancestor). The shared ancestor needs to update state according to the event data and type. This in turn causes a re-render, during which the ancestor component passes updated props to the component reading the state.
