[javascript] how to check for null with a ng-if values in a view with angularjs?

Here is a simple example that I tried to explain.

<div>
    <div *ngIf="product">     <!--If "product" exists-->
      <h2>Product Details</h2><hr>
      <h4>Name: {{ product.name }}</h4>
      <h5>Price: {{ product.price | currency }}</h5>
      <p> Description: {{ product.description }}</p>
    </div>

    <div *ngIf="!product">     <!--If "product" not exists-->
       *Product not found
    </div>
</div>
