Domain Modeling · interview question
Another engineer will maintain this code later. What choice helps the most around instance methods?
Multiple choiceMediumchapter-7-curatedpremiumdomain-modelinginstance-methods
Answer and explanation
Correct answer
B. Make the rule obvious in names, flow, and boundaries so the next reader does not have to reverse-engineer your intent.
Why
Maintainability comes from explicit intent. Candidates sound stronger when they explain why a method belongs on the object instead of in a utility module.
