Flatten object to array?

Question

I\'m using an object as a hash table. I\'d like to quickly print out its contents (for alert() for instance). Is there anything built in to convert a hash into

Answer 1

I updated this some more. This is much easier to parse than even console.log because it leaves out the extra stuff that's in there like __proto__.

function flatten(obj) {
    var empty = true;
    if (obj instanceof Array) {
        str = '[';
        empty = true;
        for (var i=0;i'+flatten(obj[i])+', ';
        }
        return (empty?str:str.slice(0,-2))+'}';
    } else {
        return obj; // not an obj, don't stringify me
    }
}

The only thing I would do to improve this is have it indent correctly based on recursion level.
