The prototype design pattern is a creational design pattern that involves creating objects by cloning them from existing ones. Its purpose is related to performance and keeping it high by trying to avoid expensive calls.
The prototype design pattern
An example class diagram
In languages such as Java, we usually see a class that implements an interface with a clone method, which returns a new instance of the class. Consider the following diagram:
In the next section, we will provide a code example of the prototype design pattern from the point of view of Scala.
