## Applicability
Use the Simple Factory pattern when you only care about the creation of a object, not how to create and manage it. Use the Simple Factory pattern when you only care about the creation of a object, not how to create and manage it.
## Disadvantages: ## Pros
* Allows keeping all objects creation in one place and avoid of spreading 'new' key value across codebase.
* Allows to writs loosely coupled code. Some of its main advantages include better testability, easy-to-understand code, swappable components, scalability and isolated features.
The code becomes more complicated than it should be. ## Cons
* The code becomes more complicated than it should be.
