});

var test = function (data1, data2) {
  console.log('test2', data1, data2);
};

XCall.addCallBack('test', test);

XCall.dispatch('test', 123, 456);
// test1 [Arguments] { '0': 123, '1': 456 }
// test2 123 456

console.log(
  'hasCallBack-test',
  XCall.hasCallBack('test', test),
  XCall.hasCallBack('test', () => {}),
  XCall.existEvent('test')
); // hasCallBack-test true false true

XCall.getCount(); // 1 (event count)

XCall.removeCallBack('test', test);
XCall.existEvent('test'); // true
XCall.getCount('test'); // 1 (callback count)
XCall.dispatch('test'); // test1 [Arguments] {}
XCall.deleteEvent('test');
XCall.getCount('test'); // 0 (callback count)
XCall.existEvent('test'); // false

XCall.setOnceEvent('test-once', test);
XCall.existEvent('test-once'); // true
XCall.getCount('test-once'); // 1 (callback count)
XCall.getCount(); // 1 (event count)
XCall.dispatch('test-once');
XCall.existEvent('test-once'); // false

XCall.getCount(); // 0  (event count)

XCall.dispatch('test-not'); // Error: not found test-not

XCall.addCallBack('hello', test); // only one callback
