Control Flow · interview question
A teammate submits shaky while loops and retries code. Which review comment is the strongest?
Multiple choiceMediumchapter-2-curatedpremiumcontrol-flowwhile-loops-and-retries
Answer and explanation
Correct answer
B. Make the rule clearer and easier to explain. Use while loops when the rule is about continuing until a condition changes, such as retries or pagination progress.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Using a while loop without a clear exit policy is one of the quickest ways to create fragile operational code.
