Domain Modeling · interview question
Which move is the best default when properties and encapsulation become part of this workflow?
Multiple choiceHardchapter-7-curatedpremiumdomain-modelingproperties-and-encapsulation
Answer and explanation
Correct answer
C. Expose state in a way that protects invariants and makes derived behavior explicit when necessary.
Why
Expose state in a way that protects invariants and makes derived behavior explicit when necessary. That is the stronger engineering move because candidates who talk about invariants instead of just 'privacy' sound more grounded. Blindly exposing mutable internal fields invites invalid state transitions later.
