At what point do you get satisfied with the knowledge you have about a programming language?

Question

With each programming language having such vast concepts, it is very difficult to know when to stop working on the theory. So how do you decide that you have learnt sufficiently well to move on to the next concept?

Answer 1

It'll take years before you can get satisfied with your knowledge of a language, but I'd say you can move from learning the theory really quickly. After you've done a beginner course, you can already move on. You'll keep learning as you move on

Answer 2

well, i would say the best is to be never satisfied and keep learning. A good programmer is always up to date to the latest changes. I guess you are referring to the Wikipedia effect. there are so many things out there, and reading one leads you to the other. I would be roughly satisfied with a language if i can write standard, not too specific, code without needing to look stuff up. Furthermore i would know about the vast majority of features the language offers. But that doesn't mean i know exactly how to do it. At one point, specific features aren't used that often. So main thing is here, you know where to look it up and that it is existent at all.
