What are the characteristics of the factory design pattern in GoLang?

The factory design pattern in the Go language has the following characteristics:

1. Simply put, the design philosophy of Go language is “concise, clear, and efficient” and the factory design pattern is also simple and easy to implement in Go language. Using the factory pattern can separate the logic of creating and using objects, making the code clearer and easier to maintain.
2. Flexibility: The factory pattern allows for the creation of different types of objects as needed, offering a flexible way to create objects without directly instantiating them in the code.
3. Encapsulation: The Factory pattern encapsulates the object creation process, hiding the specific implementation details, and providing a unified interface for external code to create objects.
4. Easily expandable: Using the factory pattern, new product classes can be easily added without the need to modify existing code.
5. Testable: The factory pattern makes code more testable by allowing objects to be created through interfaces, making it possible to use techniques such as dependency injection for unit testing.

In conclusion, the factory design pattern in Go language is simple, flexible, encapsulated, extensible, and testable, which can enhance the readability, maintainability, and testability of the code.
