Jay,

This is the only way I know how.

featureLayer.queryFeatures().then(function(results){

featureLayer.applyEdits({deleteFeatures: results.features});

});

Perfect

Is there a way to get an alert when the applyEdits is completed or successful? Want to verify its done and then write to the same FC.

Sure, applyEdits returns a promise.

  featureLayer.applyEdits({deleteFeatures: results.features}).then(results){
    //do something here
  };
});‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
