You are only getting the reference of the function but not invoking it.

alertType.save; should be alertType.save();

Also the way you defined the values in the object, you will be invoking the function immediately when the object is initialized. Instead that should be a function which gets invoked sometime in the future.

var alertType = {
  save: function() { showAlertType('Save') },
  delete: function() { showAlertType('Delete') },
};

function showAlertType(_alertType) {
  if (_alertType == 'Save') {
    alert('Save function fired');
  } else {
    alert('Some other function fired');
  }
};

alertType.save();

The later are called as arrow functions which is a `ES6` feature. https://stackoverflow.com/questions/34361379/arrow-function-vs-function-declaration-expressions-are-they-equivalent-exch – Sushanth -- Sep 28 '18 at 19:38
