A comment is a line of code that is not read by web browsers. Commenting your code allows you to leave reminders and explanations for yourself and any other coder that will be working on the page. Commenting can also be used to quickly disable parts of your code when you're testing or working on a new feature that isn't ready yet. Learning how to properly use comments will lead to more efficient coding, for you and your coworkers.
