What is the difference between git merge and git rebase?

Git merge and git rebase are both ways to integrate changes from one branch into another. Merge creates a new commit that combines the changes, while rebase moves the entire branch to begin on the tip of another branch, creating a linear history.

When should I use merge instead of rebase?

You should use merge when you want to preserve the history of your branches and show how they diverged. It's also useful in collaborative environments where multiple developers are working on the same branch.

Are there any downsides to using rebase?

Yes, rebasing can rewrite commit history, which can be problematic if others are working on the same branch. It can lead to confusion and conflicts.

Can you give me an example of when to use each?

Sure! Use merge when integrating a feature branch into the main branch to keep the history intact. Use rebase when you want to clean up your commit history before merging.
