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

if(typeof(sortOrder) != "boolean"){

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]);

Write a function that accepts an array of 10 integers (between 0 and 9), that returns a string of those numbers in the form of a phone number.

Example createPhoneNumber([1, 2, 3, 4, 5, 6, 7, 8, 9, 0]) // => returns "(123) 456-7890"
