How to sort object values in JavaScript when keys are numbers?
===

let's say I have such weird code:

    var weirdo = {};
    var producers = ['Ford','Rover','BMW','Fiat','Renault','Mitsubishi'];
    var n = producers.length;
    for(var i=0; i<n; i++) {
        weirdo[i] = producers[i];
    }
    // unknown code ???

How to sort weirdo by values? It's not array and no, I can't sort producers before filling weirdo.

Any ideas?
