Advanced Types & Utility Types - Practice

// Explore utility types!
interface Product {
  id: number;
  name: string;
  price: number;
  description: string;
  category: string;
}

// Create a form input type (all fields optional except id)
type ProductUpdate = Partial<Omit<Product, "id">> & Pick<Product, "id">;

const update: ProductUpdate = {
  id: 1,
  price: 29.99 // Only update price
};

console.log("Update:", update);

// Record type for key-value maps
type PriceMap = Record<string, number>;
const prices: PriceMap = { apple: 1.5, banana: 0.75 };
console.log("Prices:", prices);
