title: Change type of an array in typescript
body: <p>I have this type of array:</p>
  
  <pre><code>0: Client
  clientId: 405229
  clientName: "Test, Jamie"
  1: Client
  clientId: 405288
  clientName: "Test1, Jamie"
  2: Client
  clientId: 405239
  clientName: "Test3, Jamie"
  </code></pre>
  
  <p>and I basically want to convert it to be a plain array without the class like</p>
  
  <pre><code>0:
  clientId: 405229
  clientName: "Test, Jamie"
  1:
  clientId: 405288
  clientName: "Test1, Jamie"
  2: 
  clientId: 405239
  clientName: "Test3, Jamie"
  </code></pre>
  
  <p>I have tried doing: </p>
  
  <pre><code>Array.map(x=&gt; new Array(x))
  </code></pre>
  
  <p>but that produce the same result.</p>
  
  <p>any help?</p>
