What kind of data binding does Angular support?

  1. Only two-way data binding

  2. Only one-way data binding

  3. Both one-way and two-way data binding

  4. No data binding

The correct answer is: Both one-way and two-way data binding

Angular supports both one-way and two-way data binding, making it a versatile framework for managing data flow in applications. One-way data binding allows for the flow of data in a single direction, typically from the component to the view. This means that changes in the component's data are automatically reflected in the UI, but any changes made in the UI do not affect the component's data unless explicitly handled. On the other hand, two-way data binding permits bidirectional data flow, where any changes made in the UI also update the component's data. This is particularly useful for forms, where user input needs to be captured and reflected in the underlying model automatically. Angular achieves this through mechanisms such as property binding and event binding for one-way data binding, and the use of the `ngModel` directive for two-way data binding. By supporting both methods, Angular allows developers to choose the most appropriate approach based on the needs of their application, enhancing flexibility and efficiency in data handling.
