title: Assign classes conditionally in Angular2
body: <p>I'm trying to conditionally assign a class to a div based on the value I obtained from my back-end system.</p>
  
  <p>Say there is an object <code>'A'</code> which has a variable <code>status</code> which possibly has values <code>status1</code> and <code>status2</code>.</p>
  
  <p>I'm trying to assign 2 classes (<code>class1</code> and <code>class2</code>) conditionally depending on the status using Angular 2. Following is the condition I'm using. Please suggest a working alternative for this,</p>
  
  <pre><code>&lt;div ng-class="{status1 : 'class1', status2 : 'class2'}[A.status]"&gt;
     ...
  &lt;/div&gt;
  </code></pre>
