I took the course to create a desktop app with a shallow understanding of nodejs, and I think it was a very disappointing course. The instructor was so eager to make progress that more than 95% of the course was just reading the source code that he wrote. In other words, there was almost no explanation of each line of code. Of course, following the instructor and typing the code would help me learn the flow, but it was frustrating for the students because I didn't even know what it meant. In particular, when changing screens or reusing code, copying and pasting happened in the blink of an eye, so I had to stop the lecture often or rewind it, and it was also difficult to take the lecture at 1x speed. There was also the problem of not being able to focus while listening because there were frequent noises, coughs, and sighs. If you want to take this course, I recommend that you have at least a basic understanding of html, css, javascript, nodejs+express, socketio, and electron, and if you want to quickly create something practical.
