Actually, since the recommendation mentioned "programming beginners and web technology newcomers," I thought it would be a book with an easy-to-follow approach, but it was completely different. It's disappointing, but I think I've come to realize my own shortcomings. I wouldn't be able to recommend it to beginners, and it seems like a book I'd recommend to people with existing web development experience or knowledge to help them understand more deeply. If the book had been more kind, it would have been good enough for beginners to read as well. (Especially regarding code modifications, deletions, execution methods, etc.) Thank you for all your hard work with the translation.
