Which, is counter to all the cool JS libraries i've pulled into projects over the years, which naturally induced a desire to learn more JS. For shame. What this tells me is that you essentially don't care about your users. The notion of this being something only react/frontend developers care about is also quite off-base. Lets include all the "cool" JS libraries under the sun until the page is bloated, but definitely not the ones that try to make the site perform better... ? Yeah not a good attitude. Perhaps if you imagine yourself on a metered connection, navigating to a page with a bunch of hires images, wouldn't you appreciate the work the developers put into making the site a better experience for you? That respect for the user is the appeal.
