What is two-way data binding in Angular?
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 those changes, and vice versa.
Can you give me an example of how it works?
Sure! In Angular, you can use the [(ngModel)]
directive to bind an input field to a property in your component. When the user types in the input, the property updates, and if the property changes programmatically, the input reflects that change.
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 frequent updates and change detection cycles.
