“Typescript is bulletproof, I have no consistency at risk”

“…”

“guh”

Yeah... spread operator makes less and less sense to me every time I return to TS.

Never forget your typescript becomes javascript at runtime

Well I think that the spread operator and Typescript's smart tuples are an excellent combination. Although they could be a bit smarter, eg. they should be able to recognize at the very least one indeterminate length homogenous array within a tuple without coercing the extra elements at the start and end to the same type.
