What creational patterns do you know?

Creational design patterns are responsible for creating objects and managing their instantiation process. The main creational patterns are:

• Singleton — ensures that a class has only one instance and provides a global point of access to it.
• Factory Method — defines an interface for creating an object but allows subclasses to alter the type of objects that will be created.
• Abstract Factory — provides an interface for creating families of related or dependent objects without specifying their concrete classes.
• Builder — separates the construction of a complex object from its representation, allowing the same construction process to create different representations.
• Prototype — creates new objects by copying an existing prototype.

These patterns help make the code more flexible and easier to extend.
