Which move is the best default when batch helpers becomes part of this workflow?
Multiple choiceHardchapter-2-curatedpremiumfunctionsbatch-helpers
Answer and explanation
Correct answer
A. Capture repeated patterns such as chunking or fee calculation once so operational changes happen in one place.
Why
Capture repeated patterns such as chunking or fee calculation once so operational changes happen in one place. That is the stronger engineering move because good interview answers mention reduced duplication and easier testing as benefits of extraction. If each caller re-implements the pattern slightly differently, the system drifts into inconsistent behavior.
