How can I refactor my code to follow the Single Responsibility Principle?

To refactor your code for the Single Responsibility Principle (SRP), start by identifying classes or functions that have multiple responsibilities. Each class or function should have one reason to change.

Can you give me an example of a class that violates SRP?

Sure! Consider a class called UserManager that handles user authentication, user data storage, and sending notifications. This class violates SRP because it has multiple responsibilities.

How would you refactor that class?

You could create three separate classes: AuthService for authentication, UserRepository for data storage, and NotificationService for sending notifications. This way, each class has a single responsibility.

What are the benefits of following SRP?

Following SRP improves code maintainability, makes testing easier, and enhances code readability, as each component has a clear purpose.
