// Implementation

const getPrice = ({ item }) => item.price;

const normalizeItem = ({ data, options = { convert: true } }) => {
  const isTuple = Array.isArray;
  const obj = isTuple(data) ? { name: data[0], price: data[1] } : data;
  const { name, price, cost } = obj;
  const value = price ?? cost;
  const convert = options.convert && typeof value === 'string';
  const amount = convert ? parseFloat(value) : value;
  return { name, price: amount };
};

// Usage

const goods = [
  { name: 'Laptop', price: 1500 },
  { name: 'Phone' },
  { price: 25, name: 'Mouse' },
  { name: 'Keyboard', price: 0 },
  { name: 'HDMI cable', cost: 10 },
  ['Bag', 50],
  ['Case', '150'],
  ['Box'],
  { name: 'Mouse pad' },
];
goods[8].price = 5;

const output = goods.map((data) => {
  const item = normalizeItem({ data });
  const price = getPrice({ item });
  return { data, item, price };
});
console.table(output);
