Type Hints · interview question
A teammate submits shaky protocols code. Which review comment is the strongest?
Multiple choiceMediumchapter-10-curatedpremiumtype-hintsprotocols
Answer and explanation
Correct answer
C. Make the rule clearer and easier to explain. Use protocols when the code depends on a capability or method set rather than on one specific implementation.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Over-coupling to one concrete class makes testing and substitution harder than necessary.
