Thank you for your good review. In fact, those who are not looking for a developer career but are just looking to make something quickly as a hobby may not be suitable for my lecture. I am glad that you were satisfied with it even though you did it as a hobby. Haha. Each lecture is ultimately for improving the basics of a career, so there is a little bit of depth. However, if you invest enough time, it will be worth doing as a hobby. It is fun. IT is always...~~~
