Multiple choiceMediumchapter-2-curatedpremiumfunctionsfunction-extraction
Answer and explanation
Correct answer
D. Make the rule clearer and easier to explain. Extract helpers when the name clarifies one step of the workflow and the caller becomes easier to read.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Copy-pasted logic or giant helper functions usually mean the code has not decided where one responsibility ends.
