**JSON data :** 

```
  {
      "response": {
      "latitude": {
         "1": "28.5700",
         "2": "28.5700"
      },
      "longitude": {
         "1": "77.329999",
         "2": "77.3200"
      },
      "gps_location_look_up": {
         "1": "1",
         "2": "1"
      }

   }
}

```

How can one parse this json data and get these values (latitude,longitude) **using JavaScript**? How can one retrieve value of other keys?
