I find this comment incredibly condescending.

Asking "why is this on the front page?" and "...are run-of-the-mill for any CS course..." after you say "Nice writeup" isn't a compliment. It's a back-handed compliment.

Sorry, I didn't mean for it to come off that way. I genuinely meant that it was a good writeup; however, tutorials that make it to the front page (I have noticed) usually have some content that's new/uses some newer or relatively unknown technology. The author definitely has a lot of other more interesting and in-depth writeups e.g. a 3 pt fullstack series on using svelt w/a node backend (https://tahazsh.com/fullstack-app-with-svelte-and-node-part-...) that barely got attention upon HN submission.

It's just surprising that out of that content, this makes it to the frontpage. I'm not faulting the author, I'm just curious as to what insight HN readers got out of this article.

I don't think it's condescending - I clicked the link thinking it was something other than some run of the mill socket.io demo... and then that's exactly what it was. Oh well! :)

I generally agree with the commenter here, its really rare to see a tutorial article on the front page of HN (I work in NodeJS fullstack web development)

Software development is a really big space, people can be experienced in certain areas but not others.

I have a CS degree but am largely self-taught when it comes to web development; I found the article useful.

I am not certain but I think it might be social voting, where you get all your friends and neighbor to upvote on a thread. But then again HN crowd there are lot of beginning programmers.
