A common mistake that leads to a bug
I have recently written an article with a bug investigation that shows a surprising scope of variables in classes.
Today, I want to show another bug that is frequently made not only by beginners but also by some “senior” developers — mostly because of laziness.
We will try to filter a list by some criteria, what can be simpler, and how can someone generate a bug here?
