Can you explain what two-way data binding is in Angular?
Sure! Two-way data binding in Angular allows for automatic synchronization of data between the model and the view. When the model changes, the view reflects that change, and vice versa.
How does it work in practice?
In practice, two-way data binding is often implemented using the [(ngModel)]
directive in Angular forms. This binds the input field to a property in the component, so any changes in the input update the property and any changes to the property update the input.
What are the benefits of using two-way data binding?
The main benefits include reduced boilerplate code, easier synchronization of data, and a more intuitive way to manage user input and application state.
Are there any downsides to using it?
Yes, while it simplifies data management, it can lead to performance issues in large applications due to excessive change detection cycles.
