Which statement best describes good version control hygiene?

• A. Commit large batches occasionally to save time.
• B. Avoid frequent commits and skip meaningful messages.
• C. Include generated or vendor files in commits.
• D. Make small, atomic commits with meaningful messages; commit frequently; avoid including generated or vendor files.

Answer: (D)

A good version control practice is to make small, atomic commits with meaningful messages and to commit frequently, while keeping generated or vendor files out of the repository. Small, atomic commits isolate a single change, which makes the history easier to read, review, and revert if something goes wrong. Each commit should represent a distinct intent or feature, so when you or someone else looks back, the purpose of every change is clear.

Meaningful messages matter because they explain why the change was made, not just what changed. This helps future you understand the context, quickly diagnose issues, and perform precise rollbacks or code reviews.

Committing frequently prevents large, risky changes from accumulating in one place, reduces the chance of losing work, and supports reliable debugging, bisecting, and collaboration.

Avoid including generated or vendor files because they are often large, can change frequently, and can be recreated or retrieved from a dependency manager. Keeping them out of version control keeps the history clean and the repository lean, making clones faster and reviews more focused. Use ignore rules or proper dependency management to handle these files instead.
