interface -> The cloning techniques are declared in the interface. Let’s look at some important component of the above UML This is how the overall relation look like: Otherwise, the cloning method may create a child object. Each class must override the cloning method and use its class name with the new operator. The cloning method usually comprises only one line: calling a new operator using the constructor’s prototype version. If you’re updating a subclass, you must use the parent function Object() to delegate the cloning of its private fields to the super-class. The function Object() must copy the values of all class fields into the newly generated instance from the object. An alternate function Object() for a prototype class that accepts an object of that class as an argument must be defined. Make a prototype interface and add the clone function to it. How to Implement Prototypes Patternīefore we get in the code, it’s always important that we understand what are the steps to implement the prototypes design pattern. Prototypes do not engage in actual production in this situation, instead of performing a passive role. We use prototypes design patterns in real life to conduct many tests before to mass production of a product. Object class’s clone() method is an example of a Prototype Design Pattern 
We can cache the object, return its clone on the next request, and update the database as needed, resulting in fewer database calls. For instance, an object is to be constructed following a time-consuming database operation. When creating an object directly is expensive, this pattern is employed. This technique entails creating a prototype interface that instructs the current object to be cloned. We classify this design pattern as a creational pattern, since it gives one of the most effective ways to construct an object.
The prototype design pattern refers to duplicating an item while considering performance.
