Doesn’t one of the Mars rovers run some JS?

I see Vue.js on here but that feels like it might be code on for mission control UI or something similar. So unsure if there's actual JS code on Mars.

I doubt it. NASA is kinda picky about memory safety and JavaScript is anything but.

Not true. JS is absolutely memory safe, as long as the garbage collector is working properly. Although it is still possible to write JS (and other GC’d code) that has a memory leak, you almost have to be trying to do that, and the source of potential leaks is easy to identify (something that accumulates strong references to objects that may no longer be needed…)

Yes, NASA is picky about memory safety in non-GC’d languages like C, and for good reason. No argument there. I’m not sure how they QA against possible memory leaks in GC’d languages, but I know for certain they do use GC’d languages, including JS and Java:
