Commit

Summary

`git commit` saves a snapshot of your staged changes with a message — the fundamental unit of history in Git. A commit records a specific project state and points to its parent commit(s), which is what makes Git history navigable and branchable.

• 1Practice small, focused commits rather than one giant commit per day. Test it with at least one normal case and one edge case so you can explain the behavior confidently.
• 2Write commit messages in the imperative mood ('Add', not 'Added'). Validate your understanding by applying it in a small practical example.
• 3Learn `git commit --amend` to fix your most recent commit message.
