I like the approach of when finding a bug, write a test to reproduce it, fix the bug so the test passes, next do whatever refactoring you want because you have a test passing :)

To be fully transparent I donate 1 dollar a day, I just appreciate what they do, and I would like to have more services that are able to keep it that way, sadly that is not the case.

I’m just going to take the opportunity to talk about that Wikipedia is free, it doesn’t have advertisement, all the data is freely accesible and your privacy is respected, is just maintained by donations and the community. Just looking around other platforms I think they do an amazing job, so consider to donate today to keep it that way.
