If programmers have a level, how should we define them?
If programmers have a level, how should we define them? Although I have been a programmer for many years, I am not very confident in my own level. If we define them according to elementary school, junior high school, high school, and university, I think I am currently in elementary school at most. How can I improve my abilities to junior high school or higher? I would like to ask everyone for advice
