In this scenario I have a JSON object returned from a query like :

{"details": {"frequency": 2462, "data": "7839792384", "isExpensive": false}, "isConnected": true, "type": "item"}

stored in a variable myVar; and if I do console.log(myVar); I obtain all the object, so if I do console.log(myVar.isConnected); it returns true. But if i do console.log(myVar[0].data); it returns me undefined and it crashes… how can be managed this valid json object about data subitem?

Thanks in advance to all!
Cheers!
