Cool, yeah I wasn't saying that your JS was good or bad, just the possibility of it being so. I'm with you, I think you're good at JS, but then I don't really know. And neither, in truth, do you. We're both judging.
I think you need to remain open to the possibility, not just of DK but of we all have something to learn. I think I'm pretty good at JS and have popular projects and good test scores, but I also fail some JS questions (the other day in the FB PE screen I couldn't work out that the regex /^sep\n$/g wouldn't actually match. I was confused and thought the newline was needed as well as the $. Haha. Just one example.) I try to give my self a rating of 7. Keeping open to the possibility of being wrong, is more important than being right or wrong. I can't really explain it right now (maybe one reason is it's super late here, another might be I just don't know how to explain it right now) but I feel that humility is important, more so the more you know and the better your skill. Somehow I feel more humility make your skill better, especially the more skill you have.
Thanks for your humble and vulnerable example, I appreciate it! It gives you great credibility. If you were more open to the possibility of things you don't know, and not so absolutist about your JS knowledge, I would have felt you were even more credible.
Finally, you have a blindspot. You can't see that you judgement of the JS skill was actually a judgement. Because you're so sure you're right about it. Ties in with what I said before about humble and open to wrong. Of course it's a judgement, it's a "you think" it's like this, not a "it is like this". There are other perspectives that are valid. I think if you see that, then it will make wielding this big sword you have an easier and more pleasant experience! :P ;) xx
