The lectures demonstrated a practical approach through actual code implementations of iteration protocols, generators, and more, rather than simply listing theories. Additionally, it provides a broad understanding by using various languages such as Kotlin and Clojure, which I had never used before, as well as TypeScript. In this day and age, anyone can easily acquire knowledge through AI via clone coding, but I felt that the lecture provided 'metacognition' beyond that. This kind of knowledge is a valuable asset that is not easily obtained just by asking AI! In particular, the examples showing how functional programming concepts (lazy evaluation, list processing, etc.) are applied to actual business logic were very helpful. I am very much looking forward to the rest of the lecture series! I think I will be able to deepen my understanding of multi-paradigm programming through more diverse topics and advanced content! Just like the previous functional programming lecture, I felt that continuous training is necessary to truly make the concepts learned in this lecture my own. I will continue to practice by applying them to real projects! I feel that the journey to becoming a true multi-paradigm programmer has begun through these lectures.
