Day 19, and I'm pretty tired. Started chapter 5 but am pretty sure I'm going to have to re-read it again. The topic is on higher-order functions and while I get the general gist of what the author is trying to say I'm not grokking it completely. Going to try this when I'm fresher.
Today's unreleated gripe:
typeof null is an object.
And somehow the world is right again.
