When I encountered questions or problems while developing, I had no one to ask and always had to search for solutions on my own or resolve them by taking online classes. While I was able to solve many problems this way, when it came to questions about methodologies or curiosities that weren't necessarily problems, asking people around me didn't yield much benefit. For me, this course not only provided answers to those questions but also presented the reasons and rationale behind choosing those methods, making it a course that could resolve my long-standing curiosities. The 14-hour course time felt short for such a substantial course, and it felt like more than just a simple lecture—it was like receiving a wealth of know-how and tips from a senior developer. Even while watching the course, I was eagerly anticipating what useful content would appear in part 2, and now that I've finished watching the entire course, I'm looking forward to it even more.
