### **Factory Pattern**

**Description:**
The Factory Pattern provides a way to create objects without specifying the
exact class of the object that will be created. It defines an interface for
creating objects, allowing subclasses to alter the type of objects that will be
instantiated. This promotes loose coupling by eliminating the need to bind
application-specific classes into your code.

**How and When to Use It:**
- **When to Use:** Use the Factory Pattern when you require flexibility in
creating objects, especially when the exact types or dependencies may not be
known until runtime. It's useful when composing objects with complex creation
logic.

- **Example:** In a UI toolkit, you might use a factory to create different
types of buttons (e.g., `WindowsButton`, `MacButton`) based on the operating
system without changing the code that uses them.
