如何高效计算包含单品折扣和多商品满减优惠的商品最终价格？

let tb_goods = [
  {
    id: 1,
    goodsName: "A",
    price: 10,
    spceList: [101, 102, 105],

    id: 2,
    goodsName: "B",
    price: 6,

    goodsName: "C",
    price: 7,
    spceList: [101, 103, 107],
  },
  {
    id: 4,
    goodsName: "D",
    price: 7,
    spceList: [101, 104, 107],
  },
];

let tb_spce = [
