• The code is assessed based solely on its aesthetics and layout.

16. What is the role of checklists in code reviews?

• Checklists are used only for documentation purposes.
• Checklists allow code to be approved without review.
• Checklists replace the need for code reviewers completely.
• Checklists ensure a structured approach to quality checks.

17. How should feedback be given during a code review?

• Feedback should be given only when all issues are resolved, to avoid confusion.
• Feedback should be harsh and direct, ignoring the author`s feelings for efficiency.
• Feedback should be vague and brief, encouraging authors to figure it out themselves.
• Feedback should be respectful, timely, and considerate of time zones, focusing on core issues and making it a team effort.

18. What is the benefit of automating code reviews?

• Automating code reviews decreases code quality by skipping essential evaluations.
• Automating code reviews takes more time by requiring manual input for each review.
• Automating code reviews eliminates the need for any manual checks by reviewers.
• Automating code reviews can save time and ensure consistency by running tests and applying checklists automatically.

19. How should code authors handle feedback during a review?

• Authors should be defensive and argumentative about their code decisions.
• Authors should ignore feedback and trust their initial ideas.
• Authors should be open to feedback, show gratitude, and clarify expectations to ensure that all concerns are addressed.
• Authors should only respond to positive feedback and disregard critiques.

20. What is the importance of documenting decisions during a code review?

• It prevents code from being submitted if it has errors.
• Documenting decisions helps track changes and understand the reasons for comments.
