Name the patterns that are related to creational.

// Factory interface
class Creator {
    factoryMethod() {
        throw new Error("Method should be implemented by subclasses");
    }

    anOperation() {
        const product = this.factoryMethod();

// Concrete factory creating ProductA
class ConcreteCreatorA extends Creator {

    }
}

// Product interface
class Product {
    operation() {

    }
}

// Concrete product created by ConcreteCreatorA
class ConcreteProductA extends Product {

}

// Usage
const creator = new ConcreteCreatorA();

// Usage
const original = new ConcretePrototype1("value");

console.log(`Original property: ${original.property}`);
console.log(`Clone property: ${clone.property}`);

// Check that they are different objects
console.log(`Are they the same object? ${original === clone}`);
