@slightlyoff good post. more generally, in my (much less) experience, I've been shocked at just how little UX involement there is from UX folks in the web platform communities. So much of it is about developers, to the point where I think there's an over-indexing on developer needs/wants, and an under-consideration for the end user. This is less about JS specifically and more an observation on the web platform space as a whole...
anyhoos. i too hope the web can make a comeback.
