reactjs - setter setDate 不更新日期变量的状态

Question

基本上，我有一个选择器，它选择将 whichCountry 设置为该值的国家和调用 Api 的日期，该日期提取该国家的日期并将其提供给应该设置日期变量的设置器。对于其余的代码，你可以去我的repo

      const [date, setDate] = useState("");
    
    const fetchDate = useCallback(async () => {
        const data = await fetch(
          "https://api.apify.com/v2/key-value-stores/tVaYRsPHLjNdNBu7S/records/LATEST?disableRedirect=true"
        );
        const jsonDatad = await data.json();
        // jsArray=  [...jsonData];
        console.log(jsonDatad[1]["country"]);
    
        jsonDatad.forEach((element) => {
          setDate(() => {
            console.log(element["country"], whichCountry);
            if (element["country"] == whichCountry) {
              console.log(typeof element["lastUpdatedApify"]);
              return (element["lastUpdatedApify"]);
            }
          });
          console.log(date+"in")
        });
      },[whichCountry]);
      useEffect(() => {
        fetchDate();
      }, [whichCountry]);
