Q:

Accessing Child in JSON Object

I have a JSON
{
   "destination_addresses" : [ "14 Mission St, San Francisco, CA 94105, USA" ],
   "origin_addresses" : [ "23 Mission St, San Francisco, CA 94103, USA" ],
   "rows" : [
      {
         "elements" : [
            {
               "distance" : {
                  "text" : "1.3 mi",
                  "value" : 2060
               },
               "duration" : {
                  "text" : "7 mins",
                  "value" : 444
               },
               "duration_in_traffic" : {
                  "text" : "6 mins",
                  "value" : 344
               },
               "status" : "OK"
            }
         ]
      }
   ],
   "status" : "OK"
}

I have been attempting to access the "text" value of duration_in_traffic and to store that value into a variable.  For some reason I am getting the value to be undefined.  
var hold = JSON.parse(body.rows.elements.duration.text);

Why cannot I access the child like this?  

A:

You have nested arrays, so you need to access the elements in the arrays by their index.  
var hold = body.rows[0].elements[0].duration_in_traffic.text;
