There are times that a quick list of display values are needed. Maybe it's just to snoop around, or list RITMS under a request in an email. Whatever the case might be, there is an quick way to do so:
var gr = new GlideRecord('sc_task');
gr.setLimit(10);
gr.query();
var fields = 'sys_id,number,short_description,assignment_group'.split(',');
while( gr.next() ){
gs.debug( fields.map( gr.getDisplayValue.bind(gr)));
}
Result:

It works because of the bind operation being called on getDisplayValue. Without bind the call wouldn't retrieve the display values. This is because whenever a method (object.functionName) is passed in to a function, it loses the object to which it was bound. Using bind on getDisplayValue says: hey, go on your own but, don't forget you belong to me so that when you do get executed. You are executed within me and no one else. Me in this says is whatever parameter is passed into bind. In this test case it was gr.
While it has it downsides, the strategy can be useful from time to time.
Happy SNowing...
