Control Flow · interview question
A teammate submits shaky guard clauses code. Which review comment is the strongest?
Multiple choiceEasychapter-2-curatedpremiumcontrol-flowguard-clauses
Answer and explanation
Correct answer
A. Make the rule clearer and easier to explain. Reject impossible states early so the happy path is short and trustworthy.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Letting bad state flow deeper into the script makes every later line harder to reason about.
