This was a truly satisfying lecture!

After watching the basics, I'm now watching the advanced course and it feels like getting a shot of energy. If you have time, instructor, I think it would be great if you could prepare a course on object-oriented design/implementation in the AI era.

A lecture that changes your perspective on design

The speaking style was a bit stiff like a Korean language teacher, which made me feel drowsy, but the content was really excellent!

This is a must-take course for developers. It's designed for everyone from beginners to experienced professionals, with a structure that solidly builds your foundation. While taking the course, I felt validated and recognized in areas I was already good at, and when topics I wasn't familiar with came up, I could easily understand them. Looking forward to the next course!!!!

Thank you for taking the time to respond even to simple course reviews. After taking the class and thinking about separation of concerns, I had some questions, so I ended up modifying my course review. ^^; Objects are meant to handle the business logic concerns of the domain, but at this point, I don't think objects need to take on logging concerns. Should all objects receive logger objects through injection? Then would logger need to go into every object's constructor... I'm curious if there's another elegant way to handle this. Also, I think contextual information is needed when logging... Should objects internally receive contextual information as well... then would this also need to be injected? It's difficult. I would appreciate your guidance. Have a happy day today as well.

When I only read about SOLID principles in books, I couldn't relate to them, but I think I've come to understand the concepts through the example code. Thank you for such a great lecture. I want to make it my own by repeatedly watching this and previous lectures... and I'd like to share it with others as well. I have an additional question. What would be a good way to practice if I want to continuously repeat and practice?

Due to my lack of experience, I completed the course twice to finish it completely. At first, I didn't really understand what it was trying to convey, but when I watched it the second time, I thought it was a really well-planned lecture. It's truly an excellent lecture that made me realize that the code I had been writing all along wasn't object-oriented, but just code wrapped in a class shell.

Starting with "why we need to do object-oriented design," it really explains well how to do object-oriented design and even how to verify whether the design results are truly well-designed! Also, it's not just theoretical about what should be done, but it also includes example code so you can practice hands-on, which was great! If you're interested in object-oriented design, I recommend giving it a listen~

I listened well.
