Я хочу удалить все ключи, включенные в массив toRemove , из items массива объектов. поэтому я хочу получить результирующий массив объектов без всех ключей, включенных в toRemove массив

items.forEach((item) => Object.keys(item).forEach((key) => toRemove.includes(key) amp;amp; delete item[key]))

console.log(items)

Ответ №2:

Вы можете сделать это с помощью 2 петель (карта и для, в моем случае) :

 const toRemove = [
  "amount_after_regular_discount",
  "amount_after_to",
  "amount_after_activ_disc",
  "amount_after_activ_plus_disc",
  "total_advance_tax",
  "amount_after_special_discount",
  "amount_after_discount"
];

const items = [
  {
    zone: "North",
    unique_customers: "90",
    total_customers: "90",
    orders: "90",
    total_of_item_purchased_price: "429432.13",
    amount_without_discount: "415632.13",
    amount_after_to: "378418.72",
    amount_after_activ_disc: "378418.72",
    amount_after_activ_plus_disc: "378418.72",
    total_gst: "0.00",
    total_advance_tax: "0.00",
    amount_after_discount: "378418.72",
    amount_after_tax: "378418.72",
    sale_date: "2021-09-01"
  },
  {
    zone: "North",
    unique_customers: "90",
    total_customers: "90",
    orders: "90",
    total_of_item_purchased_price: "429432.13",
    amount_without_discount: "415632.13",
    amount_after_to: "378418.72",
    amount_after_activ_disc: "378418.72",
    amount_after_activ_plus_disc: "378418.72",
    total_gst: "0.00",
    total_advance_tax: "0.00",
    amount_after_discount: "378418.72",
    amount_after_tax: "378418.72",
    sale_date: "2021-09-01"
  }
];

const stripped = items.map(x => {
  for (let i = 0; i < toRemove.length; i  ) {
    const key = toRemove[i];
    delete x[key]
  }

  return x
})

console.log(stripped)
