Today I came across this post, where all the variable names were in Slovak. Obviously, when the variables are named in Slovak, it's difficult to figure out what the logic is.
Before posting this question, I found this post that mostly answers my question; except the question itself was in English, just the variable names were not. This post doesn't answer my question either, because if you remove the non-English content, there's no more code.
In this particular case, I translated the variable names to English, which may also have been the wrong move, but I wanted to know what to do for future reference.
