关于javascript:react-报错解决-Rendered-more-hooks-than-during-the-previous-render

const RenderItem = (item) => {const { children} = item;
  const [showChild, setShowChild] = useState(false);
  return (
    <>
      <div>Item!!!</div>
      {showChild && children.length > 0 && (
        <>
          // 应用一般函数会报错
          {children.map((ele) => (<>{RenderItem(ele)}</>
          ))}
        </>
      )}
    </>
  );
};

下面的代码会报错：Rendered more hooks than during the previous render.

将调用本身那行改成这种就好了：

{children.map(ele => <RenderItem item={ele} />}

依照标准，RenderItem，R 要大写
