useTransition

useTransition 是一个让你在不阻塞 UI 的情况下来更新状态的 React Hook。

import { useTransition } from "react";

function TabContainer() {
  const [isPending, startTransition] = useTransition();
  const [tab, setTab] = useState("about");

  function selectTab(nextTab) {
    startTransition(() => {
      setTab(nextTab);
    });
  }
  // ...
}
