title: Angular2 - *ngFor / loop through json object with array
body: <p>Want to loop through json object</p>
  
  <pre><code>//Defined on component side :
  jsonObj = {
      '1' : [ {"title" : "title1" , "desc" : "desc1" }],
      '2' : [ {"title" : "title2" , "desc" : "desc2" }],
      '3' : [ {"title" : "title3" , "desc" : "desc3" }],
      '4' : [ {"title" : "title4" , "desc" : "desc4" }],
      '5' : [ {"title" : "title5" , "desc" : "desc5" }]
  }
  </code></pre>
  
  <p>With <code>*ngFor</code> <strong>only on template side</strong> , 
  And <strong>without any coding (function) on component side</strong>.</p>
  
  <p>Want to print just each <code>title</code> and <code>desc</code></p>
  
  <p><strong>Is this possible ? If Yes ? How ?</strong></p>
