Er, aren't Javascript arrays 0-based?  I'd expect the same to apply to JSON.

I'd also suggest instead of
   "an inserting it again at the position "to"."
to say
   "and inserting it again so that it occupies position "to" in the resulting 
array."

This just avoids any ambiguity about whether or not "to" is specified with 
respect to the original array before removing the element to be moved.
