1. Because nobody in aerospace globally and in the history of humanity never did this before as far as I know. 2. Because many people not familiar with the exact application/industry (guilty) would assume that safety critical machines need to pass safety critical software tests/standards/languages. Javascript is definitely not known to fall in that category. 3. My main reason for thinking it was a joke when I first read it: I personally hate touchscreens (I actually use a phone with a physical keyboard on it). I would hate a touchscreen in a car, let alone a spacecraft. Let alone when I'm wearing a space-suit with massive gloves where touching the wrong button could maybe be life/death in the worse case or SUPER annoying in the best case.
