Multiple choiceHardchapter-10-curatedpremiumrefactoringtypes-during-refactors
Answer and explanation
Correct answer
B. Use types to make broad changes safer and to expose where the old contract was never actually clear.
Why
Use types to make broad changes safer and to expose where the old contract was never actually clear. That is the stronger engineering move because candidates who frame types as change-safety tools sound like maintainers, not just syntax users. Refactoring without any contract guidance can devolve into manual grep and hope.
