The Art of JavaScript Code Comments

Commenting JavaScript code is a more nuanced thing than we give it credit for. There are a couple of schools of thought on this. One states that if you feel a comment is necessary, you should rewrite it to be more legible. This is true. But it is also not true. In the process of writing a comment, you can often find things that could be written better, but it is not an either/or, for the following reason: JavaScript code can describe how, but it cannot explain why. There is just not one right way or one reason to write a comment. This session will dig into some of the many beneficial types of comments that might all serve a different purpose, followed by patterns we might want to avoid. In the process we will talk about being good teammates, collaborating, and writing the most legible JavaScript code we can.
