The Factory pattern is the second most commonly used design pattern. It is based on the idea that we can create objects of a common super type, while allowing their actual implementations to differ in subsequent subclasses.

The Prototype Design Pattern is a creational pattern that lets us create new objects by cloning existing ones instead of instantiating them from scratch.

The Builder pattern helps create complex objects step-by-step while keeping them immutable and enforcing any required rules. It avoids messy constructors, makes code more readable, and is perfect when you have both required and optional fields.

The Singleton pattern is one of the quirkiest and most trivial patterns in existence. This pattern was created to fulfil the need for a single, one-time instantiation of an object that is shared among multiple components.
