Which AngularJS feature automatically synchronizes data between the model and view layers?

Two-way Data Binding is the AngularJS feature that automatically synchronizes data between the model and view layers. With two-way data binding, changes in the model are immediately reflected in the view, and user input in the view updates the model accordingly. This bidirectional communication simplifies the code and reduces the need for manual DOM manipulation, leading to more maintainable and efficient AngularJS applications.
