What are some real-world uses of the prototype pattern?

The prototype pattern is often used in scenarios where creating an object is costly. For example, in graphic design software, you can clone existing shapes instead of creating new ones from scratch.

Can you give me another example?

Sure! In game development, the prototype pattern allows for creating multiple instances of game objects, like characters or items, by cloning a prototype instead of instantiating new objects.

How does it improve performance?

It improves performance by reducing the overhead of object creation. Cloning an existing object is generally faster than constructing a new one, especially when the object has complex initialization.

Are there any downsides to using the prototype pattern?

Yes, one downside is that it can lead to a complex structure if not managed properly, especially if the prototypes have many variations.
