It seems like you've taught me all the basics for approaching React practically. I'm using it for the first time, but I'm changing the basic structure to MS SQL and applying it to Batis, but I'm having a hard time. In practice, there are few cases where you load and input a single table like that, so there's a lot to consider. However, if you listen to it while doing general development work, it seems to be a great help. I'm also taking paid courses, but since I started using the web after the old days of ASP and PHP, I'm lacking in many ways, but there are also many parts that are fun or have evolved easily. Thank you very much.
