It is necessary to sum up the sum of all orders, i.e. inside each order, calculate the amount of goods, and then add the orders themselves.

Answer 1

const calculateFinalAmount = cart => {
  return cart.reduce((cartTotal, record) => {
    const recordTotal = record.products.reduce((recordTotal, product) => {
      return recordTotal + parseFloat(product.price) * product.quantity;
    }, 0);
    
    return cartTotal + recordTotal;
  }, 0);
};
