编写一个接受产品数组作为参数的valueStock函数

function valueStock(products) {
  let totalValue = 0;

  for (let i = 0; i < products.length; i++) {
    const product = products[i];
    const { price, quantity } = product;
    const productValue = price * quantity;
    totalValue += productValue;
  }

  return totalValue;
}

const products = [
  { name: 'Product A', price: 10, quantity: 2 },
  { name: 'Product B', price: 15, quantity: 3 },
  { name: 'Product C', price: 5, quantity: 1 }
];

const totalValue = valueStock(products);
console.log(`Total value of stock: $${totalValue}`);
