It's a masterpiece! This was the first time I've experienced a course where the message of every single lecture was so neatly organized that I could learn without any roadblocks. In the beginning, it seemed to be heading towards writing readable code. However, as I progressed, it became increasingly clear that readable code is more about maintainability than just legibility. I've had many concerns in my professional work about how to create better designs and write better code, and I feel like this course really helped me find the right direction! In particular, I loved the part about resolving polymorphism issues using overrides within enums during work.
