Commit
What Is a Commit?
A commit is a recorded snapshot of changes in a version control repository. In Git, each commit stores the state of tracked changes along with metadata such as author, timestamp, and commit message.
Why Commits Matter
Commits help teams:
- track the history of a codebase,
- review and understand changes over time,
- revert or compare changes when needed,
- collaborate safely through branch-based workflows.
What Makes a Good Commit
Strong commits are usually:
- small and focused, so each commit represents one logical change,
- well described, so the message explains what changed and why,
- safe to review, so teammates can reason about them quickly.
Atomic commits improve code review quality and make debugging easier.
