title: how to assign json strings from same dataset to different variables
body: <p>I have a data set which has a number of devices with similar properties (output). (for example 2 given below). what I do not understand is how do I take each device with the new name and assign it to for example a new div. There can be many devices in dataset. How do I tell my code to whenever there is a new device take out bytes_read and bytes_written and assign them to a new div for example assign</p>
  
  <pre><code>"bdev0": {"Bytes_Read": 0,   "Bytes_Written": 0} to div_one 
  "bdev1": {"Bytes_Read": 10, "Bytes_Written": 20  } to div_two 
  </code></pre>
  
  <p>Note that I cannot use something like data.devices[0] because there are many devices and their names keep changing, e.g bdev0, bdev1, bdev2, bde3.. 
  here is the sample of dataset given:</p>
  
  <pre><code> var data = {
          "devices": [
              {
                  "Name": "bdev0",
                  "output": {
                      "IO_Operations": 0,
                      "Bytes_Read": 0,
                      "Bytes_Written": 0
                  }
              },
              {
                  "Name": "bdev1",
                  "output": {
                      "IO_Operations": 10,
                      "Bytes_Read": 20,
                      "Bytes_Written": 30
                  }
              }
          ]
      }
  </code></pre>
  
  <p>This is how far I could come but it creates two different strings but how do I assign these separately to two different items. it sounds really stupid but I am really stuck here if for example I want to assign these strings to var a and var b how should I do it</p>
  
  <pre><code>        function myData() {
                  for (var i in data.devices){
                         var obj = new Object();
                         obj.Bytes_read = data.devices[i].output.Bytes_Read;
                          obj.Bytes_written  = data.devices[i].output.Bytes_Written;
                           var jsonString= JSON.stringify(obj);
                     console.log(jsonString)
                    }
                  }
  
      myData(data)
  </code></pre>
  
  <p>Result</p>
  
  <pre><code> {"Bytes_read":0,"Bytes_written":0}
      {"Bytes_read":20,"Bytes_written":30}
  </code></pre>
  
  <p>It gives me the data I want but I cannot figure out to assign these sets to var a and var b.  </p>
