The reason I prepared the lecture was as mentioned in the first video, but I wanted to share the knowledge I learned in graduate school. Since most of the sources of dApps are made with React, I prepared the lecture because I wanted it to be helpful for projects that need to be made with jQuery. I don't know if you took the class, but the work of changing the source code written in React to jQuery over several days is more tedious than you think. I personally hoped that it would be of some help, so I made the lecture for free and shared my knowledge, but I feel bad when I see such bad comments. As you said in the comment, when I looked at the video again, the order of the lectures was not messed up. The order of the work was changed during the video editing process, so I arranged the videos so that the students could see it more easily. I think you said that because you saw that the mynft_detail.html file was created in the folder when implementing the mynft screen. I was going to leave a comment, but I thought I wouldn't reply to the comment, so I'm leaving a comment.
