Angular 2 async pipe with ngFor loop

According to Angular 2 docs, “Angular pipes, a way to write display-value transformations that we can declare in our HTML!”

Angular 2 templates use a special Async pipe to be able to render out Observables.

Syntax:  

*ngFor="#obj of asyncObject | async | custom-Pipe: 'prop1' : 'prop2'"
OR
*ngFor="#obj of (asyncObject | async)? .prop1? .prop2"
