The HN hivemind hates JavaScript, mostly because they believe that complexity on the web is a problem self-inflicted by eager "framework devs" continuously chasing the "new shiny", which in their mind invalidates any legitimate engineering credibility or progress.
I don't care about the frameworks. I hate JavaScript because it is a security (unintentionally, and therefore intermittently) and privacy (intentionally, and therefore constantly growing) problem. And because it's necessary for more and more pages that work fine (the exact same way) with HTML and CSS alone.
