What is the clearest sign that code around instance methods should be refactored?
Multiple choiceMediumchapter-7-curatedpremiumdomain-modelinginstance-methods
Answer and explanation
Correct answer
C. When the rule is no longer easy to trace, explain, or change without breaking nearby behavior.
Why
A refactor is justified when the code stops communicating its intent. Keep behavior on the object when it mainly exists to answer a question about that object's own state.
