Comments are, to put it mildly, a controversial topic.
There are two very strong opinions in software development, both extremely popular and widespread. The first one states that comments are evil, and you should not use them under any circumstance. The main argument is that instead of using comments, you
Arguments play a very important role in the readability of a function. When implemented properly, they show intent and provide information about the function's behavior.
