i absolutely hate how the modern web just fails to load if one has javascript turned off. i, as a user, should be able to switch off javascript and have the site work exactly as it does with javascript turned on. it’s not a hard concept, people.
but you ask candidates to explain “graceful degradation” and they’ll sit and look at you with a blank stare.
I don’t understand why we are blaming the stealing info part on JavaScript and not the tech industry. Here is an article on how you can be tracked (fingerprinted) even with JavaScript disabled. As for slow websites, also blame the tech industry for prioritizing their bottom line over UX and not investing in good engineering.
