Rebase

Summary

`git rebase` replays your branch's commits on top of another branch's latest history, producing a cleaner, linear history than a merge would. Rebase rewrites commit identities, so it is powerful for cleaning up local history but requires care whenever other people already depend on those commits.

• 1Rebase a feature branch onto an updated `main` and compare the log to a merge. Validate your understanding by applying it in a small practical example.
• 2Learn the golden rule: never rebase commits that have already been pushed and shared. Focus on understanding the underlying reason it works, not only memorizing the definition.
• 3Practice an interactive rebase (`git rebase -i`) to squash a few commits together.
