Answer 3

You put comments to make the CODE itself more readable when editing it. It's especially useful when you code with other people (example: here is this section, here's this other one which is blue for this reason etc.) or as notes for yourself to keep things in order and easy to understand when you open your own code and some time passed. It's a memory refresher :)
