socket.in wasn't behaving as advertised (broadcasting to all rooms). I decided to take matters into my own hands.

if(typeof(sortOrder) != "boolean"){        
    return items;
}
filtered.sort(function (a, b) {
    if(sortOrder == true){
        return (CustomOrder(a.status) > CustomOrder(b.status) ? 1 : -1);
    }
    else if(sortOrder == false){
        return (CustomOrder(a.status) < CustomOrder(b.status) ? 1 : -1);
    }
});

The status property is a string ("Started", "Running", "Failed", "Finished", etc.), and CustomOrder is a function with a switch that just returns a predefined integer for each string. I switched CustomOrder to just be a simple lookup table object, and the sort call was changed to filtered.sort((a, b) => CustomOrder[a.status] - CustomOrder[b.status]);

this program take a string from you and give you a Desirable-hash by changing lower to upper and changing lower to upper if that possible

final int two_fifty_five_hex = 0xFF
final int two_fifty_five_dec = 255

One is in hex but the other is in decimal! Watch out, make sure you use the correct 255, not the other 255.

There are two methods findSplitVariable. Second one takes extra parameter (varIdx) that is not used anywhere.
