All you have to fear is fear itself.
One suggestion I have is, if you have learned any functional programming in your studies or work, look into how it applies in JS. JS is, you see, a functional language masquerading as an imperative one. My big breakthrough in understanding came when someone gave me the (simplistic but useful) advice to treat JS as 'LISP with C-like syntax'. IOW, understand functions as first-order data, and start passing them as parameters to functions, etc. Start thinking of polymorphy in mathematical terms rather than OOP terms. Compose rather than inherit to create classes.
