When I’m exploring a problem I end up with complex tree of many anonymous branches as I try different solutions to a problem and they all show up in my jj log and it’s so easy to refer to them by stable change ids. Often I’ll like part of a solution but not another part so I split a change into 2 commits and branch off the part I like and try something else for the other part. This way of working is not nearly as frictionless with git. A lot of times I do not even bother with editor undo unless it’s just a small amount of undoing because I have this workflow.
Git is to jj like asm is to C: you can do it all with git that you can do with jj but it’s all a lot easier in jj.
Within a day of switching I was fully up to speed with jj and I never see myself going back. I use colocated repos so I can still use git tools in my editor for blaming and viewing file history.
Sure even rebasing a complex tree in git can be done by creating an octopus merge of all leaf nodes and rebasing with preserve merges but like that’s such a pain.
