So how is this different from git worktrees exactly ?
replies(2):
author me tions that git cli require multiple steps when there are unstaged changes.
I don't know if git has one liner cli command for it as i myself use gitextn to create worktrees
It's easy to get this impression because git is so dominant, so most people using jj use it as a frontend to git.
But jj is a fully self-contained version control system. It always stores all its commits, branches, and other repo metadata in the .jj directory. You can use it standalone like this without ever using git.
Git integration is optional, and works by importing from or exporting to Git. Internally, jj still manages its own history. Git support is just a bridge.
