Git Diff in Git & GitHub
`git diff` shows line-by-line what changed between versions. It displays removed lines (with -) and added lines (with +). This is useful before committing to make sure you're committing the right changes.
You can compare your current work to the last commit, or any two commits. It's like a detailed "before and after" view.
