I can't understand the syntax: (componentRef.instance)

Question

I am studying how to create a component dynamically in Angular. I can't understand the syntax:

(<AdComponent>componentRef.instance).data = adItem.data;

Can someone explain it?

With this line (<AdComponent>componentRef.instance).data = adItem.data;

In fact you tell to TS the instance is type of AdComponent it's only this.

So in your components who is loaded dynamically the @Input() data is a AdComponent like this

@Input() data:AdComponent
