Object - Design Principles

Personally, it was a bit challenging but a truly excellent lecture. I couldn't fully grasp it in one go, so repeatedly listening extended my study period. Thank you for the great lecture; I hope future courses include more live coding 😊😊

In a world flooded with lectures teaching only specific library/framework usage, this lecture is paramount for truly teaching the unchanging essence of object-orientation. Also, he refactors code based on crucial principles, and if one truly understands object-orientation like him, there'd be no need to study design patterns separately. For the next lecture, I'd personally like to see how these principles apply with Spring and JPA. I'd also like to see him live code. Thank you.

It's an honor to leave the first review. After completing `<Object - Basics>`, I immediately took `<Object - Design Principles>` as well and am now writing this review. The advantages of the course are as follows: 1. It's easy to understand intuitively because it's not just listing principles but includes actual code examples. ㄴ I thought I knew the SOLID principles because I encounter them often, but after watching the lecture, I realized that was my misconception. 2. Convenience has increased compared to `<Object - Basics>`. ㄴ A link to the relevant repo is provided through the course materials, making it easy to access. ㄴ The presenter is no longer visible, making the presentation much easier to see. There are also some slightly disappointing aspects (They are minor). 1. The volume level differs slightly for each video, which is a bit distracting. 2. There are also cases where there are errors in the videos. 3. If colloquial phrases like '되게 됩니다.' were refined, it would feel tidier. 4. There are instances where the notation for foreign words differs (e.g., 메서드/메소드), and it would be a bit tidier if this were unified. I highly recommend watching `<Object - Basics>` as well. It allows for a broader understanding of the course. If you don't know what object-oriented design is, I strongly recommend this course. I plan to recommend it to many people around me as well 😊😊 Thank you to Jo Young-ho for planning this great course. I expect my code to change significantly in the future. Work less, earn more 😊😊😊

It's exciting like watching a movie, as the story about design continues~ I'll keep listening carefully~ Thank you for the good lecture!

Following the basic course, this seems like the best lecture on object-oriented programming. It is very substantial as it is composed of well-structured content from concepts to examples.

I really enjoyed the lecture. I thought I knew the design principles well, but unexpectedly, there were many things I had misunderstood. Explaining using code made it easy to understand. I was unsure how to refactor code, but after the lecture, I was able to establish some clear criteria. Thank you for creating a great lecture!

The lecture content was good, and I was impressed by how you drew diagrams to help us understand during Q&A sessions! Thank you for such an excellent lecture. However, it's regrettable that students expend unnecessary energy because the lectures are not conducted via live coding. The reasons for the energy expenditure due to the lack of live coding, which I felt while watching the lectures, are as follows: 1. Unexpected code omissions in PPTs or materials. If it were live coding, the IDE would have caught errors, preventing issues. 2. While you showed methods changing mid-lecture, I was curious how constructors changed and tried to follow along with the code, but the provided code is the completed version at the end of each session, so the code differs. 3. Details on dividing code into packages were omitted and only present in the completed code. I'm unsure about the perspective of students who only understand by observing, but for those typing code along with the lecture, these points were inconvenient. While it's fine for review in multiple sessions, it was regrettable that energy was consumed beyond simply understanding the lecture. In short, it felt more like reading a good book than leveraging the benefits of a VOD lecture. However, since the lecture content itself was excellent, I thank the instructor for providing such a great lecture.

After taking the lecture, I also came across the book and even looked for follow-up lectures. I am learning a lot. Thank you for sharing your valuable experience and skills.
