Last time we finished with a change only in the working tree, one which I don’t want to keep. It is possible to just manually revert your changes but it is much quicker to use git.

A couple of definitions
When you add changes with the git add command you are adding to the
index. What you add from is called the working tree, this is the
current state of the files in your file system.

Why use a version control system (VCS)?
Have you ever tried to add a new feature to, or change (refactor) an
existing part of, a piece of software (or improve a section of a
document) and eventually realised that you made it worse and you
aren’t sure how to get back to where you started? Perhaps, to avoid
such a situation, you now have cluttered directories filled with
my-code-v1, my-code-v2-plus-that-other-feature etc., etc. and you’re
not quite sure which one does what you want. Version control will help
you to keep a log of your changes as well as snapshots of the code as
you apply them; it will also allow you to collaborate far more easily
but, for now, we will focus on a single editor and a linear history.
