title: Length of json object in handlebars template
body: <p>Is it possible to get the length of json object inside the handlebars template using the property .length .<br>
  {{json.length}}<br>
  If not is it possible to find the length based on the list of keys and then using the .length such as
  {{json.keys.length}}</p>
  
  <p>Sample JSON structure</p>
  
  <pre><code>{1232134235423:[Name,Destination,Desc],  
   2134213214321:[Name],  
   2342354356634:[Name,Desc]
  }
  </code></pre>
  
  <p>Edit 1:I know this can be achieved by using a custom helper but this length has to be used inside custom if helper. So something like array.length would be useful</p>
