title: Else statement in Angular
body: <p>How does angular2 propose to render</p>
  
  <pre><code>&lt;div *ngFor="let todo of unfinishedTodos"&gt;
      {{todo.title}}
  &lt;/div&gt;
  </code></pre>
  
  <p>in case if <code>unfinishedTodos.length &gt;0</code></p>
  
  <p>and text "empty" in another cases.</p>
  
  <p><strong>P.S.</strong></p>
  
  <pre><code>&lt;div *ngIf="unfinishedTodos &amp;&amp; unfinishedTodos.length &gt; 0"&gt;
      &lt;div *ngFor="let todo of unfinishedTodos"&gt;
          {{todo.title}}
      &lt;/div&gt;
  &lt;/div&gt;
  &lt;div *ngIf="!unfinishedTodos ||  unfinishedTodos.length &lt;= 0"&gt;
      empty
  &lt;/div&gt;
  </code></pre>
  
  <p>looks ugly</p>
