An example of an AI chatbot conversation about data binding and directives in web frameworks.
What is the difference between data binding and directives in frameworks?
Data binding refers to the synchronization between the model and the view, while directives are special tokens in the markup that tell the library to do something to a DOM element.
Can you give me an example of data binding?
Sure! In Angular, you can use two-way data binding with the [(ngModel)] directive to bind input fields to a model.
And what about directives? How are they used?
Directives in Angular can be structural, like *ngIf or *ngFor, which change the DOM structure based on conditions or iterations.
Are there any performance implications when using them?
Yes, excessive use of directives can lead to performance issues, especially if they cause frequent DOM manipulations.
