title: Angular 2, split data from Json
body: <p>Hi I have a json from http request, the server json response is this:</p>
  
  <pre><code>{
    "map": {
      "03/04": 13,
      "05/04": 41,
      "06/04": 1,
      "12/04": 4,
      "14/04": 7,
      "18/04": 8,
      "19/04": 2,
      "22/04": 1,
      "25/04": 4
    },
    "links": []
  }
  </code></pre>
  
  <p>I want to split dates in 1 array and values in other array,
  At the end I want :
  Data[03/04,05/04,06/04....] and
  Val[13,41,1....]
  is it possible without difficult implementation?</p>
