I keep JS off by default* and it's teriffic. Using a browser with it enabled is tedious, slow and distracting in addition to the obvious heka-less-secure.
I see my colleague making a web app that forces the browser into 100% CPU on scroll, just to animate a shrinking nav bar. Also a page that wont settle in for 15 seconds until assets from Google Fonts downloaded and all scripts have run. So I secretly pray for a draconian anti-js order imposed on us, even though my minimal Vue scripts will go away.
