Count items in loop

1

I am trying to get the total number of items in my *ngFor?!

<li *ngFor="let order of Ordersummary | async; let i = index; let last = last; let first = first">
    {{Ordersummary.length}}
</li>

{{Ordersummary.length}} is showing Unresolved variable length

I got it:

count as totalCount;
