angularjsHow do I add an event listener in AngularJS?

To add an event listener in AngularJS, you can use the $on function. This function takes two parameters, the event name and a callback function. The callback function will be executed when the event is triggered.

// example
$scope.$on('eventName', function(event, args) {
    // do something
});

The callback function will receive an event object and an argument object. The argument object contains the data associated with the event.
