You need to iterate both the groups and the items    each   takes a collection as first parameter and data response venue tips groups items text tries to point to a string  Both groups and items are arrays   Verbose version     getJSON url  function  data            Iterate the groups first        each data response venue tips groups  function  index  value                Get the items         var items   this items     Here  this  points to a  group  in  groups              Iterate through items            each items  function                  console log this text      Here  this  points to an  item  in  items                            Or more simply     getJSON url  function  data          each data response venue tips groups  function  index  value              each this items  function                  console log this text                               In the JSON you specified  the last one would be      getJSON url  function  data           Get the  items  from the first group      var items   data response venue tips groups 0  items          Find the last index and the last item      var lastIndex   items length - 1      var lastItem   items lastIndex        console log  User      lastItem user firstName         lastItem user lastName       console log  Date      lastItem createdAt       console log  Text      lastItem text         This would give you      User  Damir P    Date  1314168377   Text  ajd da vidimo hocu li znati ponoviti

You re not looping over the items  Try this instead     getJSON url  function data         each data response venue tips groups items  function  index  value            console log this text

I think you need something like   var text  data response venue tips groups 0  items 1  text
