Examples
// A series of ee.DateRange objects.
var dateRange1 = ee.DateRange('2017-06-24', '2017-07-24');
var dateRange2 = ee.DateRange('2017-07-24', '2017-06-24');
var dateRange3 = ee.DateRange('2017-07-24', '2017-07-24');
// Determine if the ee.DateRange is empty.
print('Is dateRange1 empty?', dateRange1.isEmpty());
print('Is dateRange2 empty?', dateRange2.isEmpty());
print('Is dateRange3 empty?', dateRange3.isEmpty());
