Creational Patterns
Creational patterns are a category of design patterns in software engineering that focus on object creation mechanisms, aiming to create objects in a manner suitable to the situation. They abstract the instantiation process, making systems independent of how their objects are created, composed, and represented. Common examples include Singleton, Factory Method, Abstract Factory, Builder, and Prototype patterns.
Developers should learn creational patterns to improve code flexibility, reusability, and maintainability by decoupling object creation from usage, especially in complex systems where object creation logic varies. They are crucial when dealing with families of related objects, controlling object instantiation (e.g., ensuring a single instance), or constructing complex objects step-by-step, such as in GUI frameworks or database connection management.
