What helps you identify between the two? What I have come up with, Classes are related to school and Periods (".") are related to school as well. Thanks!

I guess one way you can remember at least the # is using the concept of twitter hashtags, where you can have only unique hashtags. But other than that, this is just one of those things you need to memorize, and to be quite honest, it is very simple to remember, you just have to use them more often so that it gets ingrained into your memory.
Also, can I ask why you are asking this as a JavaScript question? This is mainly for CSS and unless you are using querySelector isn't really applicable to javascript.
