问为什么钩子的初始值不能为空对象？

EN

export interface faceProduct {
  readonly title: string;
  readonly prodState: string;
  readonly shipping: string;
  readonly sold: string;
  readonly alt: string;
  readonly material: string;
  readonly location: string;
  readonly src: string[];
  readonly color: string[];
  readonly saiz: string[];
  readonly price: string;
}

export interface faceProductList extends faceProduct {
  readonly id: string;
  readonly to: string;
}

 const [prod, setProd] = useState<faceProductList>({});

 const [prod, setProd] = useState<faceProductList>(Object);
