Really great in-depth article! At this point in my life I feel like there's such a large amount of content for "beginners" written by people who have only been coding for five years, and a huge dearth of "intermediate" content for people who are adults, and who do know how to code, but who would benefit from being walked through the deeper parts of the language, and this article really fits into that sweet spot for me.
