Answer 1

Вы можете использовать функцию .find в JavaScript, для поиска необходимого вам продукта:

const products = [
  { name: "Radar", price: 1300, quantity: 4 },
  { name: "Scanner", price: 2700, quantity: 3 },
  { name: "Droid", price: 400, quantity: 7 },
  { name: "Grip", price: 1200, quantity: 9 },
];
    
function calculateTotalPrice(productName) {
    const product = products.find(p => p.name == productName);
    return product.price * product.quantity;
};
    
console.log(calculateTotalPrice('Radar'))
