Guarantees about re-rendering and setState batching inside an event handler

Hi,
I have React 17 and I am using hooks. I believe answer is hinted by "Multiple updates inside event handlers get batched into a single update." ... https://reactjs.org/docs/implementation-notes.html#what-we-left-out , but I am not 100% sure I understand it correctly.

Does React guarantee that while my event handler is being processed no re-render happens? That is first re-render happens after my event handler exits.

  const onClick = () => {
    setState1(1);
    // do some stuff
    setState1(2);
    // do some stuff
    setState4(4);

    // no-rerender will ever be called by React until this point (that is until function returns) ???
    // re-render is only scheduled to happen ASAP
  } 

Thanks for answering :)

Commencez par lire les notes d’implémentation de React liées et par vérifier le comportement de batching des gestionnaires d’événements de React 17 décrit dans la question. Déterminez si la documentation doit énoncer une garantie concernant le moment des re-renders et le batching de setState, puis mettez à jour la documentation pertinente une fois le libellé et la portée prévus confirmés.
