Learn Javascript for Unity?

I want to start to learn to write my own code completely from scratch for unity but at the moment the bast i can do is looking at code i've found online and trying to work out how everything works. I'd rather go to somewhere that teaches Js specifically for unity and not just Js in general. I've already been on codecademy for a bit and i've learnt the basics but now that it is getting more complicated the instructions given seem to be becoming more vague and hard to follow. So yeah can anyone help me it would be so much appreciated as I would be able to stop having to rely on the internet for code so much Also needs to be free.

 

Look up Academy of Art university, they teach it there, even have online schooling, not sure if that's something you are interested in.
However they teach in C# not JS.
Just forwarding that to you, not sure if it's useful.

(P.S. - It is a College) But they do teach it, nothing wrong with going to college! lol.
