Do you have a line of code may not be obvious to the next reader? Just add a comment. Unsure if you will need that method for later? Save it for later in a comment block. I would argue that all of these examples are not good uses of comments. So what are comments good for? If you ask me, not much.

In this session, you'll learn some of the problems with comments as well as some refactoring strategies that can enable you to not have to write them in the first place.
