Subject [jira] [Resolved] (COUCHDB-1776) for in with array make string index instead of int
Date Wed, 24 Apr 2013 20:03:17 GMT


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".
