What is Two-Way Data Binding in AngularJS?

Two-way data binding in AngularJS is a mechanism where changes to the model (data) in the view are automatically reflected in the controller, and vice versa. This means that any changes made to the model in the view will be immediately updated in the controller, and any changes made in the controller will be reflected in the view.

How Does Two-Way Data Binding Work in AngularJS?

AngularJS uses a process called the digest cycle to achieve two-way data binding. When a change is made to the model in the view (such as through an input field), AngularJS automatically updates the corresponding value in the controller. Similarly, if a change is made in the controller, AngularJS updates the view to reflect these changes.

By using two-way data binding, AngularJS simplifies the process of keeping the model and view in sync, resulting in a more efficient and intuitive development experience.
