Answer 1

We can use JSON.stringify and JSON.parse together to recursively remove blank attributes from an object.

jsObject = JSON.parse(JSON.stringify(jsObject), (key, value) => {
               if (value == null || value == '' || value == [] || value == {})
                   return undefined;
               return value;
           });
