Windows.ApplicationModel.Contacts.js

if(typeof Windows != 'undefined') {
  // Create the picker 
  var picker = new Windows.ApplicationModel.Contacts.ContactPicker(); 
  picker.desiredFieldsWithContactFieldType.append(Windows.ApplicationModel.Contacts.ContactFieldType.email);
  // Open the picker for the user to select a contact 
  picker.pickContactAsync().done(function (contact) { 
    if (contact !== null) { 
      var output = "Selected contact:\n" + contact.displayName; 
      console.log(output); 
    } else { 
      // The picker was dismissed without selecting a contact 
      console.log("No contact was selected"); 
    } 
  });
}

Line 12 is missing .log after console

console.log("No contact was selected");

@UziTech, thank you, finally fixed it...
