js restructure object to elevate property
<p>I have the following array with objects:</p>

<pre><code>[
   {
        "timestamp_start":{"S":"2016-11-28T10:35:48.100Z"},
        "timestamp_stop":{"S":"2016-11-28T10:39:48.100Z"},
        "deviceId":{"S":"0"},
        "userId":{"S":"0"}
   }
]
</code></pre>

<p>The S property indicates that the value is a string. I do not need this information later on and would like to drop it and rather 'elevate' the value one level to get the following array:</p>

<pre><code>[
   {
        "timestamp_start": "2016-11-28T10:35:48.100Z",
        "timestamp_stop": "2016-11-28T10:39:48.100Z",
        "deviceId": "0",
        "userId": "0"
   }
]
</code></pre>

<p>I already tried some variations with Object .map .keys .values but failed to get a nice solution.</p>
