Yes, this is JavaScript, and yes it didn't work. Found while reviewing some code

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

This developer was trying to force the browser to download a custom image rather than show it inline, so he coded an open reverse proxy and attempted to release it to a production web app. Also, all exceptions are trapped and shown to the user in plaintext in their browser.

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]);
