Does it manage to support floats? I am not sure if those can be safely used in the UEFI environment. (I recall GRUB’s build of Lua being integer-only, and Linux avoiding the use of floating-point arithmetic in kernel mode, but I don’t remember the reason.)
What if it makes me recoil in horror? screams into the void
Can someone break this down for me? Looks like it's using... C? to load a js interpreter which bootstraps an API around all UEFI features? Do I have that right? And, if so, does that mean that once the API has been bootstrapped, one could actually write an OS in js? Or are there other abstractions that would need to be migrated first?
Earlier quoted context omitted.
Why not?
Because this can end very badly. It is a new surface to attack

I bet somebody has done that.

Seems like a small number of hobbyists have attempted.
I've heard of people doing this with other high level languages. Basically you need enough low level code to bootstrap a VM. Once you have that, you can make the high level language decide some logic that traditionally would be in C code, like manipulating page tables or whatever.

Oh hey, we've reached the "Metal" stage! https://www.destroyallsoftware.com/talks/the-birth-and-death...
Mind you I never said anything about quality or performance, obviously doing everything in JavaScript comes with it’s own issues but if you were to say that someone got JavaScript running in the Linux kernel as a POC I wouldn’t even be surprised
