How do I check maintainability?
Understand the concept
Maintainability means another developer can understand and safely change the code without discovering hidden dependencies. Clear responsibilities, names and contracts reduce the chance that a small change breaks unrelated behavior. Abstraction helps when it removes a real duplication or dependency, not merely when it adds more classes.
Important ideas
-
Prefer clear names, small responsibilities and explicit dependencies.
-
Remove duplicated business rules and unexplained constants.
-
Add types where they clarify real inputs and outputs; avoid unnecessary abstraction.
-
Prefer a small explicit function over a generic framework if only one straightforward behavior is required.

- Explain how your suggested refactor makes a likely change or test easier, rather than arguing only from personal style.
