What are the best practices for separation of concerns in software development?

Separation of concerns is a design principle for separating a computer program into distinct sections, each addressing a separate concern. Best practices include using modular design, adhering to the Single Responsibility Principle, and implementing design patterns like MVC.

Can you explain the Single Responsibility Principle?

The Single Responsibility Principle states that a class should have only one reason to change, meaning it should only have one job or responsibility. This makes the code easier to maintain and understand.

How does separation of concerns improve code maintainability?

By separating concerns, you reduce complexity, making it easier to understand, test, and modify individual components without affecting others.

What are some common design patterns that support separation of concerns?

Common design patterns include Model-View-Controller (MVC), Observer, and Strategy patterns, all of which help in organizing code by separating different responsibilities.

Can you give an example of applying separation of concerns in a web application?

Sure! In a web application, you can separate concerns by having distinct layers: the presentation layer (HTML/CSS), the business logic layer (JavaScript), and the data access layer (APIs). This way, each layer can be developed and maintained independently.
