What is the impact of cohesion on software development?

Cohesion refers to how closely related and focused the responsibilities of a single module are. High cohesion within a module means that its components work well together, which enhances maintainability and understandability.

Can you give me examples of high and low cohesion?

Sure! An example of high cohesion is a class that handles all operations related to user authentication. In contrast, low cohesion might be a class that manages user authentication, file uploads, and email notifications all together.

How does cohesion affect code maintainability?

High cohesion improves maintainability because changes in one part of the module are less likely to impact others. This makes it easier to update and debug the code.

What are some best practices to achieve high cohesion?

Best practices include keeping modules focused on a single responsibility, using clear naming conventions, and regularly refactoring code to improve structure.
