Design patterns are a collection of reusable solutions to complex design problems in software development which evolved over time and widely accepted as the best way to address certain design challenges. They're more suitable when building an application prototype or working on large and complex projects. Design patterns are classified into three categories based on the type of problem they can solve  1. Creational design patterns  2. Structural  design patterns  3. Behavioral design patterns  Creational design patterns Creational design patterns are a type of design pattern that focus on creating objects in a way that is flexible, reusable, and efficient. These patterns provide a set of guidelines for creating objects and managing their lifecycle, helping to ensure that objects are created and used in a consistent and effective way.  Some most common examples of creation design patterns are  1.  Singleton pattern 2. Factory pattern 3. Abstra...
