Thanks to the fast-paced coding, I had fun listening to it. Just before I took this course, I took another course where the instructor did live coding on the latest technology stack lineup, but that course was a bit impromptu, so it was a bit difficult for the students to follow the flow. But this course was much easier to follow in order, so it was good. I think he prepared each lecture a lot. I saw him use Thunder Client during the course, so I installed the extension right away. It's convenient because I can send requests in VS Code without installing Postman. When writing comments, if you write them in JS Doc format like '/** */' instead of '//', the comment content will be displayed when you hover over the editor, which was a nice little tip. Please teach us more about this when you release another course. + There are some negative opinions about learning Chakra-ui in the course reviews, but I think a little differently. Chakra UI is evaluated as a well-made UI library, and many developers refer to it when designing components, and it seems that the usage is not much different from other UI libraries. For those who have used UI libraries so far, there will be almost no learning curve, and for those who have not used UI libraries so far, I think it would be a good opportunity to learn about a well-made UI library. I would like to recommend this front-end lecture to those around me because it is fun and provides practical tips. Thank you for the great lecture.
