How does AngularJS update the view in response to user events handled by controllers?

AngularJS updates the view in response to user events handled by controllers through two-way data binding. Two-way data binding is a powerful feature that automatically synchronizes the model and view. When the model changes as a result of a user event, such as a form input, the view is updated automatically, and vice versa. This seamless synchronization simplifies the development process and enhances the maintainability of AngularJS applications.
