Eloquent JavaScript Chapter 15

I’m currently working through chapter 15 of Eloquent JavaScript. The chapter walks through a project for making a simple mario-type game. Previously, if I had trouble understanding something, I would go through and write out all the code. I did that for this chapter, but I’m still trying to connect some of the pieces.

I’m going to keep grinding through for now, because I heard reading code helps you improve as a programmer. Plus, this is an opportunity to read code written and organized by someone who seems really accomplished and good at what he does.
