I will also never understand how JavaScript development has gotten so complicated with seemingly zero benefits. It takes minutes to do a "frontend build" and the output grows larger all of the time. I bumped into some Angular crap that was hundreds of megabytes somehow, and still AJAX fetched the same info 4x on page load because the "MVCC" or whatever it's called didn't even buy them the abstraction of using the same values multiple times on one page...
