The past few days I've been trying to take advantage of weird windows of time to work on my JavaScript. I'm working through chapter 3 of Eloquent JavaScript. I'm finding it a little quicker than most books about programming languages because it goes over a lot of concepts rather quickly. I kinda like that because it's part refresher and part "we'll get to that later". Also it lays out some of the blueprint of what we'll cover in later chapters.
Trying hard not to break the chain of learning containers as well. Getting a full half-hour can be tough, but I'm finding it worth it.
