• Function factories can create objects with configurable properties, useful for generating standardized objects with specific defaults.

function createProductFactory(defaultCategory) {
  return function(name, price) {
    return {
      name: name,
      price: price,
      category: defaultCategory,
      getProductInfo() {
        return `${this.name} costs $${this.price} and belongs to ${this.category} category.`;
      }
    };
  };
}

const createElectronicsProduct = createProductFactory('Electronics');
const createClothingProduct = createProductFactory('Clothing');

const product1 = createElectronicsProduct('Laptop', 1000);
const product2 = createClothingProduct('T-shirt', 20);

console.log(product1.getProductInfo()); // Output: Laptop costs $1000 and belongs to Electronics category.
console.log(product2.getProductInfo()); // Output: T-shirt costs $20 and belongs to Clothing category.
