What do you wish to know about JavaScript when you were in university?

Hey guys!

I was asked if I would like to make a couple of lectures at the university about plain JavaScript (basics). And I would love to but I'm not sure where to start.

So here we are. Some of us are years after school/uni and some of us are still there. What do you wish to know about JavaScript when you were in university? And what would you like to say to students right now?

Any tips, help, ideas or even articles are welcome!
