In a similar vain, what is the value of r in:let [z,y,...r] = {0:0, 1:1, 2:2, length: 3, 3:3,4:4}; should it be [2] or [2,3,4] (and if the latter how is that determined)? It seems to me that [2] is the right answer,
How so? If `...n` is the range slice operator, it should be [2, 3, 4], no? Dmitry.
and if that is the cause, consistency requires that for the first problem z gets the value undefined.
