I am new to js & this is a js code snippet which I am trying to understand

_myFunc: function (object, object2) {
  console.log(object);
  $('.divevent').keydown(function (event, object, object2) {
    console.log(object);
    if (event.shiftKey && event.keyCode == 9) {

The first console.log. gives us right data but the second console.log prints out undefined.
