Of course I downvoted him because I disagreed with what he was implying! Downvotes are not just for burying trolls, but meant to be a mean of expressing how much you agree with a comment (the opposite of an upvote).

in the last part, my emphasis was on the word everything. If you divide that comment into two different comments (first being 'misleading article' and second, (implicitly) 'I don't want to learn CS, though I write code in JS regularly'), I'd up vote the first and down vote the second comment.

It is true that his decision does not affect anyone else, but I don't believe that even such decisions can't be criticized. And I'm arguing that his decision of not wanting to learn a dialect of a language he uses on a daily basis (that would take a very short time) is not a good one, and is un-hackerish. If he had taken time to learn and have decided that CS is not for him, I neither would've down-voted him, nor would I comment on his decision.

I'm sorry if I wasted your's or any one else's time by my comments on this unimportant matter. I know that HN's comment section is meant to be a place for constructive arguments, but I couldn't help it. I read that an unseen friend is doing something that I think is really wrong, and I can't help mentioning it.
