Honestly, if a complete beginner listens to this, they might understand the initial part, but in the middle, unknown concepts suddenly pop up here and there, so you might have to search and study them. Nevertheless, I highly, highly, highly, highly recommend it. Especially, if you have some JS knowledge or are reviewing, this lecture teaches you the overall mechanism of how JS is used on the web, so personally, it's one of the most valuable lectures on Inflearn. I listened to it to review JS because I had to do a project, and the lecture was so informative that I felt I had to write a review. 👍👍 (Maybe because the lecturer hasn't done many lectures? The voice is a bit high-pitched and stiff..?)
