jj is very flexible when it comes to workflow. One thing to note is that commits don't have to have messages. What I tend to do is to run `jj new` frequently while I work on something and leave all of them without messages. Then when I'm ready to make my actual commit, I squash the temporary commits together and then add a message. If my changes are separable, I can split the commits before squashing. This workflow acts as a kind of undo history. I can easily go back to what I had 5 minutes ago and try a different approach, but then also jump back to my original changes if I want. It makes experimentation much easier compared to git.
