I had a limited access for some time and the computer I was using blocked Javascript EVERYWHERE. I cannot tell you how many websites weren't available to browse or were displayed horribly. I went to my own website, forgetting that I started to rely heavily on JavaScript more and more for styling.
Some of the stuff was okay but the most recent pages were a calamity. So when I got back to my place, I decided to take off all JS from my website. It's quite difficult but I'm working on replacements and there's some I'm pretty proud of. So yeah, cleaning JS and changing all the related HTML and CSS.
Quite extreme but living with a machine that locked JS was reall eye opening on the modern web. My site should be available on these machines.
