A lecture where you can learn the 'multi' paradigm. I've worked with many languages and frameworks over the years, but it's been a long time since I've experienced programming that focuses on the paradigm itself as much as this lecture. It reminds me of when I was learning functional programming a few years ago. The way it explains object-oriented/functional/imperative programming was very impressive. I was able to think structurally about the iterator pattern, and it was a valuable time because I was able to learn practical ways to use it. I was able to experience how programming languages expand thinking, rather than just learning the language itself. I highly recommend this to anyone who wants to make a new turning point in their current coding style.
