๐ Angularโs GoF patterns. Factory Method.

Advantages:
โ Flexibility and expandability: Allows for easy introduction of new types of products without changing existing code.
โ Reducing dependencies: The Factory Method reduces the direct dependency between classes that create and use objects, making code modification and testing simpler.
โ Ease of maintenance and updates: Code using the pattern is easier to maintain and update, as adding a new type of product often doesnโt require changes to the existing code that uses the factory.
Disadvantages:
โ Complex architecture: Using Factory Method can complicate application architecture, especially when used unnecessarily or in simple scenarios.
โ Code bloat: Creating many factory methods and classes can overload the code, making it hard to understand, particularly for new developers.
โ Performance issues: In some cases, particularly with incorrect implementation, Factory Method can affect application performance due to additional method calls and object creations.
โ Debugging difficulty: Following this pattern can make debugging harder since the actual object creation is hidden within the factory method, complicating error tracking.
โ Need for careful planning: Effective use of Factory Method requires detailed planning and understanding of when and what objects should be created. Planning errors can lead to incorrect or excessive implementation.
โ Limited flexibility in some scenarios: While Factory Method provides flexibility in object creation, it can be limited in scenarios requiring very dynamic or conditional object creation.
โ Not suitable for simple applications: For small or simple applications with a relatively static structure, using Factory Method might be unnecessary and complicate the project.
