title: Angular 2 return html instead of string
body: <p>Let's assume I have a <code>test</code> property like that:</p>
  
  <pre><code>export class SomeComponent implements OnInit {
  
      testing = '&lt;strong&gt;Just testing&lt;/strong&gt;';
  
  }
  </code></pre>
  
  <p>And I add to my test.component.html this line:</p>
  
  <pre><code>{{ testing }}
  </code></pre>
  
  <p>The output will be <code>&lt;strong&gt;Just testing&lt;/strong&gt;</code>. I want it to return <strong>Just Testing</strong>. How can I do that?</p>
