title: Why use ng-template instead of just *ngIf
body: <p>Any reason to use:</p>
  
  <pre><code>&lt;div *ngIf="show; else notShow"&gt;content&lt;/div&gt;
  &lt;ng-template #notShow&gt;other content...&lt;/ng-template&gt;
  </code></pre>
  
  <p>Instead of:</p>
  
  <pre><code>&lt;div *ngIf="show"&gt;content&lt;/div&gt;
  &lt;div *ngIf="!show"&gt;other content...&lt;/div&gt;
  </code></pre>
