By default git diff works on entire lines, but try this:

    git diff --word-diff=color --word-diff-regex=.

It highlights only the parts that have actually been changed/added/deleted.

I think a diff is just as valuable with this code. Of course understanding a diff also requires understanding the code but if you’re interested the repository is linked at the root of this thread so you could poke around.

Yes. The diffs tend to be quite small & obvious.
