Prototype is a creational pattern that lets you copy existing objects without making your code dependent on their classes. Instead of creating a new object from scratch, you ask an existing object — the prototype — to clone itself. The clone can then be modified independently.
ℹ️Core idea: delegate cloning to the objects themselves. Each class implements a clone() method, so the caller never needs to know the concrete class — it just calls clone() on the interface.
