Select2: Why code demo copied don't work?

I have 10.000 row data to load in select.
improve performance I thought to load them with the "query" constructor.
I wanted to start from the example "e5" (Loading Data) on the documentation page.
I have also added demos of all "e10" - "Loading Array Data"

Except the first element "e10" all the others do not work. Who can help me ?
Where am I wrong?

$(document).ready(function() {

  $("#e5").select2({

    minimumInputLength: 1,

    query: function(query) {

      var data = { results:  },

        i, j, s;

        

      for (i = 1; i < 5; i++) {

        s = "";

        for (j = 0; j < i; j++) { s = s + query.term; }

        data.results.push({ id: query.term + i, text: s });

      }



      query.callback(data);

    }

  });



  $("#e10").select2({

    theme: "classic",

    data:[{id:0,text:'enhancement'},{id:1,text:'bug'},{id:2,text:'duplicate'},{id:3,text:'invalid'},{id:4,text:'wontfix'}],

  });



  var data=[{id:0,tag:'enhancement'},{id:1,tag:'bug'},{id:2,tag:'duplicate'},{id:3,tag:'invalid'},{id:4,tag:'wontfix'}];



  function format(item) { return item.tag; }



  $("#e10_2").select2({

    data: { results: data, text: 'tag' },

    formatSelection: format,

    formatResult: format,

    theme: "classic"

  });



  $("#e10_3").select2({

    data: { results: data, text: function(item) { return item.tag; } },

    formatSelection: format,

    formatResult: format,

    theme: "classic"

  });

  

  $("#e10_4").select2({

    data: function() { return { text: 'tag', results: data }; },

    formatSelection: format,

    formatResult: format,

    theme: "classic"

  });

I've removed some unnecessary/unrelated libraries and styling to reduce the example to the bare minimum that still shows the problem.

I've removed some unnecessary/unrelated libraries and styling to reduce the example to the bare minimum that still shows the problem.
