Don't Get Obsessed With Design Patterns - Simple Programmer:



"The cost of adding a design pattern

There are many different design patterns, but most of them have something in common: when you apply them, you need to lay out some structure. In other words, you need to add classes and/or interfaces to the code.

In the first example, this structure consists of an abstract class extended by two children classes. What’s more, in order for the old code to use these new classes, you also need to make some updates not directly related to the design pattern itself.

The moral of the story is: if you’re thinking about applying a design pattern, consider the cost of doing so and the potential benefit. Doing it only for the sake of doing it will make your code more complex than it needs to be."
