any one can help, I want to get the count of group by view in SharePoint List using JSOM, below is my code, I can access the view which is group by item (Created), but not getting count filed.

function sharePointReady(){

        getItemsFromView("Receipts", "axix3",
         function(items){
             for(var i = 0; i < items.get_count(); i++){
                 var item = items.get_item(i);

                console.log(item.get_item('Created'));
             }
         },
         function(sender,args){ 
             console.log(args.get_message())
         });
    }



function getItemsFromView(listTitle, viewTitle,success,error)
{
    var ctx =new SP.ClientContext.get_current();
    var list = ctx.get_web().get_lists().getByTitle(listTitle);
    var view = list.get_views().getByTitle(viewTitle);
    ctx.load(view,'ViewQuery');
      ctx.executeQueryAsync(
        function() {
            var viewQry = "<View><Query>" + view.get_viewQuery() + "</Query></View>";
            getItems(listTitle,viewQry,success,error);
        },
        error);
}

function getItems(listTitle, queryText,success,error) 
{
    var ctx =new SP.ClientContext.get_current();
    var list = ctx.get_web().get_lists().getByTitle(listTitle);
    var query = new SP.CamlQuery();
    query.set_viewXml(queryText);
    var items = list.getItems(query);
    ctx.load(items);

    ctx.executeQueryAsync(
        function() {

            success(items);
        },
        onQueryFailed
   );
}

function onQueryFailed(sender, args) {

    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}
