Flow of the course. I recently came across Ionic, and I decided that the current course is the most suitable for me, so I am taking the course. There are a few things I would like to see resolved. 1. Flow of the course > It may be a problem with the video editing(?), but I saw that the flow of the course was disrupted here and there. > For example, when a course is being taught with content A, it suddenly switches to course B and then back to A. 2. Sound quality > The volume is not constant. > It suddenly goes down and then suddenly goes up. It may not be easy to resolve right away, but if possible, please resolve it~ㅜ I think the rest of the courses are pretty good. However, since most students who do not have a MacBook use the CLI commands that are different from the ones in the course. I would also like to show this part by inserting commands for Mac and Windows in the middle of the video. For example, the npm rm command starts with rm on Mac, but on Windows, you have to enter the command as npm rm to run it. I've only completed about 40% of the course, but I believe it will be of great help in the future.
