Data Binding in AngularJS

Data binding in AngularJS is a powerful feature that allows the synchronization of data between the model and view components. It eliminates the need for manual DOM manipulation and ensures that any changes to the model are automatically reflected in the view, and vice versa.

One-way Data Binding

In one-way data binding, the data flows only from the model to the view or from the view to the model, but not both ways. Any changes made to the model will be reflected in the view, but changes in the view will not be propagated back to the model automatically. This can be implemented using expressions such as {{ expression }}.

Two-way Data Binding

Two-way data binding, on the other hand, allows for the synchronization of data in both directions - from the model to the view and vice versa. Any changes made to the model will reflect in the view, and any changes made in the view will update the model instantly. This can be implemented using ng-model directive in AngularJS.

Overall, data binding in AngularJS simplifies the development process by automatically keeping the model and view in sync, making it easier to build dynamic and responsive web applications.
