javascript – How to alphabetically organize a select obtained through a JSON?

Question:

I set up a select through JSON below, the only problem is that it follows the order of the key, how to organize it alphabetically?

{
    "12": "Acre",
    "27": "Alagoas",
    "16": "Amapá",
    "13": "Amazonas",
    "29": "Bahia",
    "23": "Ceará",
    "53": "Distrito Federal",
    "32": "Espírito Santo",
    "52": "Goiás",
    "21": "Maranhão",
    "51": "Mato Grosso",
    "50": "Mato Grosso do Sul",
    "31": "Minas Gerais",
    "15": "Pará",
    "25": "Paraíba",
    "41": "Paraná",
    "26": "Pernambuco",
    "22": "Piauí",
    "33": "Rio de Janeiro",
    "24": "Rio Grande do Norte",
    "43": "Rio Grande do Sul",
    "11": "Rondônia",
    "14": "Roraima",
    "42": "Santa Catarina",
    "35": "São Paulo",
    "28": "Sergipe",
    "17": "Tocantins"
}

$(document).ready(function() {
  $.getJSON("/estados.json", function(estados) {
    $.each(estados, function(codigo, nome) {
      $('select#estado').append($('<option>').text(nome).attr('value', codigo));
    });
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="estado" name="estado" class="form-control input">
  <option value="">Selecione o Estado</option>
</select>

Answer:

First I would like to suggest an edit of your Json so that the return is readable, someone can mess with the code that one day it won't be you! So I would do something along the lines:

var UFs =    
[ 
    {Id: 12, UF: "Acre"},
    {Id: 27, UF: "Alagoas"},
    {Id: 16, UF: "Amapá"},
    {Id: 13, UF: "Amazonas"},
    .
    .
    .
];

After that I would make a very simple sorting function:

function OrdenarPorNome()
{
      UFs.sort(function (a, b) { return a.UF > b.UF ? 1 : -1; });
} // Como  o amigo acima já observou!

function OrdenarPorID()
{
      UFs.sort(function (a, b) { return a.Id > b.Id ? 1 : -1; });
} 

Even if you want to sort by Id too!

To perform the ordering, just call the function:

OrdenarPorNome();
