extract partial attributes of an object using typescript types

Question

how to extract partial attributes of an object using typescript types? is it even possible?

export interface Product {
  brandName: string;
  modelNo: string;
  rate: number | null;
  someOtherProp1: string;
  someOtherProp2: string;

}


export interface OrderItem {
  modelNo: string;
  rate: number;
  qty: number;
}

const exampleProduct: Product = {
  brandName: "Example Brand",
  modelNo: "12345",
  rate: 100,
  someOtherProp1: "Some Value 1",
  someOtherProp2: "Some Value 2"
};

Then how can i create an instance of order item from product, i tried following which does not work:

const exampleOrderItem: OrderItem = {
  ...exampleProduct,
  qty: 10
};
