Thanks for that. I appreciate it. Two quick followups:
1. What is the semantics (and name) of using the ? (e.g as in ds?.data()
or ds?.output) in the example
2. How do you access a specific child. (e.g. how do I get at ds2 as in
below)
<data-service id="ds1">1,2,3</data-service>
<data-service id="ds2">4,5,6</data-service>
<span>Hello, there
<span [textContent]="name"></span>
<button (click)="ds?.data()">hit me {{ds?.output}}</button>
</span>
