I was thinking that if we wanted, we could add some extra features to the makefiles, such as:

• optional tests parameter for make test
• linting only the changed files

However, this repository is so small that linting and testing all the files is very quick, so perhaps that is more trouble than it is worth.

yeah, I'd like to make that you could type make test -- path/to/files or something which would just run those specific tests / lints but I haven't hand the willpower to check if it would even be possible without $VARIABLES :P

for the lint, my personal syntax preference would be make lint.changed but dunno what we collectively land on 🤔

and probably not worth for this repository 👍
