Im going to make an effort at learning javascript. I often use jQuery but i really don't know anything about how to customize the different scripts etc that im using, and i want to be able to write my own stuff.
Im currently studying webdevelopment on UNI lvl but there is a lack of JS courses in the program, its not as much about front-end that i would like.

So anyone have any good tips for on resources for learning Javascript?

thanks in advance
