What a misinformed article lol. While it is obviously bad practice to use while wait() do in cases when a conditional could easily be substituted into the while statement (like the example provided in the doc), there are many cases like the example provided by @Urxpaly45 where it really doesn’t matter and— in fact— increases readability.
Acting as if someone is “a bad programmer” (as the article states) simply for following a certain convention— irrespective of the circumstances surrounding the use case— proves the only bad programmer is the one peddling this misinformation. And exposes their lack of critical thinking skills.
while wait() do is a tool in your coding arsenal. Good programmers know when to use it and when not to. Bad programmers read opinion and accept it as doctrine.
