title: Angular2 Count items inside of the array display information
body: <p>Here again, I have the following component MyStoreComponent</p>
  
  <pre><code> export class MyStoreComponent {
      stores: any[] = [{
          storeId: "456392",
          location: "New York",
          people: [{
              manager: "John",
              sales: "Claudia",
              tech: "Marcel"
          }, {
              manager: "Martin",
              sales: "Jenn",
              tech: "Oliver"
          }]
          }, {
          storeId: "456393",
          location: "California",
          people: [{
              manager: "Kim",
              sales: "Nancy",
              tech: "Marie"
          }]
      }];
  
   }
  </code></pre>
  
  <p>Now I am looking to count the people inside of each branch. For example 456392 has two manager or  456393 just have one</p>
  
  <p>I tried myself with</p>
  
  <pre><code> &lt;ul *ngFor="#store of stores"&gt;
      &lt;li *ngFor="#person of store.people"&gt;
          &lt;span *ngIf="person.length &gt; 1"&gt;Show this&lt;/span&gt;
      &lt;/li&gt;
   &lt;/ul&gt;
  </code></pre>
  
  <p>But I am losing in some point, any help? please?</p>
