Randall Leeds resolved COUCHDB-1776.
------------------------------------
Resolution: Invalid
This is actually according to language specification. For-in statements on
Arrays iterates string-coerced keys. It works when you use it in code as an
index into the array because myArray[i] when i is a string or an integer is the
same (it is coerced). If you are just outputting the value of i into, for
example, a CouchDB map result, it will be a string and this is expected. It is
not a bug. Try it in any browser or in node.js REPL and you will get the same
thing. typeof(i) is "string".
> for in with array make string index instead of int
