MarcusSioux — You have learned quite a bit. Keep it up. I thought I’d throw in my two cents. Along with your courses, you might want to study data structures and algorithms. Here is an intro in Javascript https://www.amazon.com/dp/1783554878. Its not the typically recommended book, but since the focus is on JS, I thought I’d mention it.

If you like that course and want to delve into computer science, then here is a free Computer Science course by Harvard http://online-learning.harvard.edu/course/cs50-introduction-computer-science

Best of luck !
