title: Creating an array of a class Angular 2
body: <p>I need to create an array of a class using Angular 2 and TypeScript.</p>
  
  <pre><code>import { ClassX } from '...';    
  
  public ListX: ClassX[];
  </code></pre>
  
  <p>Once I have the list, I want to then add more empty instances of <code>ClassX</code></p>
  
  <pre><code>action() {
    this.ListX.push(ClassX);
  }
  </code></pre>
  
  <p>This would then add a new <code>ClassX</code> instance to the front end</p>
