So how is this different from git worktrees exactly ?

there is no difference as jj is only a frontend to git.

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

That's not really true in this case, as the worktree feature from jujutsu is not implemented on top of git worktrees.

wtf? it can diverge from git?

wasn't git compatibility it's main pro?

You can still use git worktrees in a colocated repository. jj workspaces are a different, but similar capability that provide some extra features, at the cost of some others.

Yes, jj is its own VCS with pluggable backends.

Google uses it with Piper, their centralized VCS.

Being compatible and being purely a frontend aren’t the same thing.

To be technical, it's more that it can read and write the on-disk Git format directly, like many other tools can.

I think the easiest way to conceptualize it is to think of Git and jj as being broken down into three broad "layers": data storage, algorithms, user interface. Jujutsu uses the same data storage format as Git -- but each of them have their own algorithms and user interface built atop that storage.

git is the storage layer. JJ's commands do not have to, and never did, match git one-to-one.

No, that's just a practical approach to supporting migration to jj.

If we want to improve systems, we need to be able to migrate conveniently from older systems to better ones.
