This is kind of an odd construction. At any rate TS can't tell that [].length
is always 0 (it's just checking the .length
of something with an array type, which in general could be anything) so as far as the compiler is concerned uploaded
could still be nullish after this check
from typescript.
Thanks for tracking this as "Design Limitation". 👍
