Can the React docs state more rule of the custom Hook

Could the custom Hook page https://reactjs.org/docs/hooks-custom.html
include one important rule:

https://github.com/reactjs/reactjs.org/pull/3557

Does any change of state in a custom Hook cause any component that uses it to re-render? Yes, when we use any Hook in our function, this function becomes a custom Hook, and when other components use it, any update of the state in this custom hook can cause the component to re-render. So we should not think of the custom Hook as a static function.

Or something along that line? Right now, it feels really magically that somehow, we define a function and it can magically cause another component to re-render itself.

A working example might even be added: https://codesandbox.io/s/suspicious-keller-blqey?file=/src/App.js

Examinez d’abord la page sur les Hooks personnalisés à l’adresse https://reactjs.org/docs/hooks-custom.html ainsi que la pull request associée #3557. Confirmez l’explication prévue selon laquelle les mises à jour d’état entraînent le nouveau rendu des composants qui utilisent un Hook personnalisé, puis mettez à jour la documentation avec la formulation ou l’exemple convenu et vérifiez que la page s’affiche correctement.
