What are some common function design patterns in programming?

Common function design patterns include the Factory, Singleton, and Observer patterns. Each serves a unique purpose.

Can you explain the Factory pattern in more detail?

Sure! The Factory pattern creates objects without specifying the exact class of object that will be created.

What about the Singleton pattern?

The Singleton pattern ensures a class has only one instance and provides a global point of access to it.

Are there any real-world examples of these patterns?

Yes! For instance, the Logger class often uses the Singleton pattern to ensure a single logging instance.
