Short does not recognize entire date

Question

Hello, how do I make the short recognize the whole object

{
  "Dir": "Sd:/",
  "List": [
    {
      "Tipo": "P.O.S.-",
      "Data": "11/10/2017",
      "Hora": "23:58",
      "Size": "0",
      "Nome": "Arquivo1"
    },
    {
      "Tipo": "P.-.-.-",
      "Data": "12/05/2017",
      "Hora": "23:57",
      "Size": "0",
      "Nome": "Arquivo2"
    },
    {
      "Tipo": "P.-.-.A",
      "Data": "14/10/2017",
      "Hora": "23:57",
      "Size": "0",
      "Nome": "Arquivo3"
    },
    {
      "Tipo": "P.-.-.-",
      "Data": "16/12/2017",
      "Hora": "23:57",
      "Size": "0",
      "Nome": "Arquivo4"
    },
    {
      "Tipo": "P.-.-.-",
      "Data": "29/09/2017",
      "Hora": "23:57",
      "Size": "0",
      "Nome": "Arquivo5"
    }
  ],
  "NArq": "0",
  "NPast": "5"
}

I want to organize the object "Date" in order of last modification.

var a = a.Data.toLowerCase();
var b = b.Data.toLowerCase();
return a < b ? -1 : a > b ? 1 : 0;

It only detects the first number, but not the rest :/

To organize an array of Date you have to use timestamps and not the text version of a date. It uses the .getTime() and it will already work as you want. You will have to convert this Data and Hora in an object Date only before making the conversion to timestamp.

Example:

function converterData(data, hora) {
  var partes = data.split('/').reverse().map(Number);
  partes[1]++;
  var hm = hora.split(':').map(Number);

  return new Date(partes[0], partes[1], partes[2], hm[0], hm[1]).getTime();
}

function ordenarDatas(a, b) {
  a = converterData(a.Data, a.Hora);
  b = converterData(b.Data, b.Hora);
  return a < b ? -1 : a > b ? 1 : 0;
}

var desordenado = {
  "Dir": "Sd:/",
  "List": [{
      "Tipo": "P.O.S.-",
      "Data": "29/09/2017",
      "Hora": "23:58",
      "Size": "0",
      "Nome": "Arquivo1"
    },
    {
      "Tipo": "P.-.-.-",
      "Data": "29/09/2037", // <-- 2037!
      "Hora": "23:57",
      "Size": "0",
      "Nome": "Arquivo2"
    },
    {
      "Tipo": "P.-.-.A",
      "Data": "29/09/1997", // <-- 1997
      "Hora": "23:57",
      "Size": "0",
      "Nome": "Arquivo3"
    },
    {
      "Tipo": "P.-.-.-",
      "Data": "29/09/2017",
      "Hora": "23:59",
      "Size": "0",
      "Nome": "Arquivo4"
    },
    {
      "Tipo": "P.-.-.-",
      "Data": "29/09/2017",
      "Hora": "23:57",
      "Size": "0",
      "Nome": "Arquivo5"
    }
  ],
  "NArq": "0",
  "NPast": "5"
}

var ordenado = desordenado.List.sort(ordenarDatas);
console.log(ordenado);
