Like? This isn't explained, I'm curious on why I would want to use it, but this is just an empty platitude, doesn't really give me a reason to try.

Say you start on Main, then make a new branch that you intend to be a PR someday. You make commit 1. Then another. Maybe 6 more. Now you realize that something in commit 1 should have been done differently. So, you "edit" commit 1. All the other commits automatically rebase on top and when you go back to your last commit, it's there. Same with _after_ you PR and someone notices something in commit 3. Edit it, push, and it's fixed.

You can do all that in Git, but I sure as hell never did; and my co-workers really appreciate PRs that are broken into lots of little commits that can be easily looked over, one by one.

I do this every day in git. “git rebase -i [hash]” fyi.

you think you do, but you don't; jj edit is much, much better than an edit step in a rebase - it essentially keeps rebasing while you're editing, so you can always see which changes get conflicts, then you are free to resolve them, or not, at your convenience.

So you get all merge conflicts at once? How is that better?

it's exponentially better because you don't need to resolve them until you're ready. conflicts are committed to the local repo like everything else, commits with conflicts are noisily warned about and you can fix them whenever instead of having no other option than immediately.

To the sibling comment that is too deep to reply to, this covers why delayed conflict resolution is advantageous: https://news.ycombinator.com/item?id=45084835

It’s for other branches that hang off the commit that introduced the conflicts.
