Is it possible to have feature definitions toggle depending on whether a query is emtpy?

I want to do something like this:

definition.selectedBodies is Query;
if ( isQueryEmpty(definition.selectedBodies ) ){
      definition.someOtherProperty is boolean;

IE, i want to provide some other inputs, but only if the user has entered a query that selects things.

I tried 

if ( definition.selectedBodies != undefined ){ 

but it appears that even when the user selects nothing, we get an empty query, not undefined ( unfortunate )

i know i can do this too:
but it kind of stinks beause the user has more clicks:

definition.doYouWantToDoWhatever is boolean;
if ( definition.doYouWantToDoWhatever  ){
     definition.selectedBodies is Query;
     definition.someOtherProperty is boolean;
