JavaScript Can't assign a variable immediately from subscribe() canvas,canada,cancelled,canceled vs cancelled,cancun,canada goose,cane

You want to make sure the data can be accessed; otherwise you'll try to read from an undefined property. There are a few ways to do this:

<b>Customer name: </b> {{order?.customerName}}<br>

This will still display Customer name: with nothing. Instead you may want to use ngIf with else to show a loading indicator or something like that.

<div class="img-right" *ngIf="order$ | async as order; else loading">
  <b>Customer name: </b> {{order.customerName}}<br>
</div>
<div #loading>Loading...</div>

Note that order probably shouldn't be an input. You will need an order$ property:

order$ = this._ordersService.getOrder(1);

The | async takes care of the subscribe and unsubscribe for you.

Answer:1

You can use ? operator: order?.customerName

Answer:2
