I have been chatting with several people recently and everyone has their own views on being active. In addition, many people who are unfamiliar with terms of analysis due to some standard issues have mixed up a lot of information such as being active and retaining. later I found that this is a very real problem. In my opinion, none of the problems have become problems. Therefore, I would like to talk about active things here to help more developers wh
