}
Your array already is more-or-less just an object, but arrays do have some "interesting" and special behavior with respect to integer-named properties. The above will give you a plain object.
edit oh also you might want to account for "holes" in the array:function toObject(arr) {var rv = {};for (var i = 0; i < arr.length; ++i)if (arr[i] !== undefined) rv[i] = arr[i];return rv;
}
