SRP

The SRP is a fundamental concept in software design. It advocates that when defining a class to provide functionality, that class should have only one reason to exist and should be responsible for only one aspect of the functionality. In simpler terms, it promotes the idea that each class should have one job or responsibility, and that job should be encapsulated within that class.

Thus by adhering to the SRP, you are essentially striving for classes that are focused, cohesive, and specialized in their functionality. This approach plays a crucial role in enhancing the maintainability and comprehensibility of your code base. When each class has a well-defined and single purpose, it becomes easier to manage, understand, and extend your code.

Of course, there is no obligation for you to follow the SRP. But knowing about the principle and thinking about your code with that in mind will improve your code base over time.

In practice, applying the SRP often leads to smaller, more...
