Maybe more so than most learning, I find that coding takes you actually having to doing it in the form of projects no matter how small (stubs and full fledged). Repetition and referring back to your notes, seeing it happen and thinking about it is the only way for me. Thinking about it, playing with it. Your beginner projects can be updated as you learn further concepts.
That being said, if you have taken good notes, with Screen Shots and/or example code, keep going with JS. Keep moving ahead and applying what has been covered. My advise.
