I was impressed by the Time Travel.

If I delete a file through there, and "go back in time" would the files would still be there?

Yup. The time travel stuff is somewhat transparent and hard to talk about. If you think of the document as a .js file, than it is pretty easy to reason about what will happen. Things are just executed in order. The magic is that we don't have to re-execute a bunch of stuff every time just to get to your actual change.

Wouldn't that mean it's opaque, since we can't see see into it?

PS. That's picky. This is a rad project and I love the time travel & the 'requiring packages automatically installing them' feature too.

Do you override 'require('fs')' or do you do some magic at the OS level ?

We use docker pretty extensively, and so between each code cell we can evaluate the layered filesystem docker provides for changes and save them.

Good, thanks.
