Yes, the part you pointed out is the third time I've heard it in the course review. ^^; When I recorded this lecture, it was my first time taking an online lecture, and on top of that, I didn't have time to edit the original data I recorded because of childcare. Of course, it would be nice to do it very well from the beginning, but not everyone can do it well from the beginning. Starting from the second lecture, those issues were almost resolved. ^^; For those who will come in the future, please know that I'm editing the lectures whenever I have time. I've already finished editing the first lecture and uploaded it again. Thank you for the good point, and I hope you become a great developer. Thank you.
