Describe the process of handling global events in AngularJS controllers and its effect on application performance.

  • Global events in AngularJS controllers are automatically handled by the framework
  • Global events in AngularJS controllers are not possible for performance reasons
  • Global events in AngularJS controllers can be handled using $rootScope
  • Global events in AngularJS controllers can only be handled through external libraries
In AngularJS, handling global events in controllers can be achieved using $rootScope. While $rootScope provides a way to broadcast events globally, developers should be cautious about its impact on application performance. Broadcasting global events can lead to increased coupling between components and potential performance bottlenecks. Understanding the trade-offs is essential for maintaining a well-performing AngularJS application.
