const backUrl = "https://626d63f2e58c6fabe2d4dc9a.mockapi.io/items"

function Main() {
   const [items, setItems] = useState([])
    useEffect(() => {
      async function fetchItems() {
        const response = await fetch(backUrl);
        const data = await response.json();
        console.log("EffectUsed")
        setItems(data)
      }
      fetchItems()
    }, []);
}

同时，在渲染和重新渲染期间，钩子会触发 2 次。我不知道该怎么办了
