Disappointing points 1. There are many parts where errors are fixed later -> If you are someone who frequently presses save and checks the screen, you may spend a lot of time troubleshooting errors, wondering 'Why isn't it working?', but you should be careful and take the course because the parts that are fixed later are shown in the video. Good points 1. Before each video starts, they clearly explain 'This is how it will be implemented' and start, so you can understand the design and functions in your head while following the code. 2. They prepare countermeasures for various errors in advance, and they are meticulous and kind enough to not copy and paste even easy codes but to do it one by one. 3. Considering the price of the course, it is the best course composition. Review I took this course after learning Java and having basic coding skills and not knowing React, and then I took Nomad Coder's ReactNative beginner course. If I had to compare, the course composition was really good. I felt like I learned everything I needed to implement to some extent. It took me a while to listen to the end because it was my first time with React, but if I had basic React and CSS, I think I could have understood it quickly just by listening to the part about creating an Instagram app. Thank you for the great lecture.
