I recently did a free course on Udacity that I thought was really well done and wanted to share it with you guys!
The course is on design patterns and it starts off by going over regular old spaghetti coding and shows you how to refactor into an MVC format without a framework, while showing you the advantages the MVC paradigm provides. It then goes over the KnockoutJS framework lightly to show you how a framework can help you use this layout. It ends with a bit of info on reading other code and getting to know how to understand it.
I was having trouble understanding how to organize my code better and how these frameworks help, and this course really did the job perfectly. I highly recommend checking it out if you have already gained a decent familiarity with Javascript through your coursework here or elsewhere and want to take things to the next level.
