How does two-way data binding in AngularJS facilitate the implementation of reactive user interfaces?

Two-way data binding in AngularJS facilitates the implementation of reactive user interfaces by automatically updating the user interface (UI) in response to changes in the underlying data. When the model changes, the view is automatically updated, and vice versa. This eliminates the need for manual DOM manipulation and event handling, making it easier to create reactive and dynamic UIs. Understanding this aspect of two-way data binding is crucial for building modern and responsive user interfaces in AngularJS.
