Your right... The more I think about it...
Number.range(from=0, to=Number. MAX_SAFE_INTEGER)
Is probably best, as a signature, then using .map(...) If you want a string
representation...
For that matter, wouldn't mind seeing more of the array utility methods,
like map, added to strings, iterating through each character, same as
.split('').map, but that's another discussion.
