Reviewing diffs
Reviewing diffs
A diff is a compact explanation of the difference between two versions. Reading it before committing catches accidental edits and makes collaboration kinder.
Learning objectives
- Inspect unstaged and staged changes
- Recognize accidental edits
Inspect what changed before asking others to review it. Focus on explaining each decision in your own words before relying on a pattern or shortcut.
Example
git diff
git diff --stagedSummary
KEY TAKEAWAYS
- Diff review is a quality check.
- Staged and unstaged changes are different sets.
