I have this simple JSON file (test.json):

{personnes:[

            {

                name:Super,

                firstname:Mario,

                adresse:[45 rue du poirier,6700,Strasbourg],

                departement: bas-rhin,

            },

            {

                name:Super,

                firstname:Luigi,

                adresse:[10 rue du muguet,6700,Strasbourg],

                departement: eure,

            }

]}

For some reasons, I need to get each departement values to be stored in a single array like this :[bas-rhin,eure]

I learned that $.makeArray() can do the job, but didn't find out how. Here is my jQuery :

$( document ).ready(function() {

    $.getJSON( ajax/test.json, function( data ) {

        console.log('loaded');

        var departement;

        var departements = $.each(data.personnes, function (index, personne) {

            departement = personne.departement;

            var arr = $.makeArray(departement);

            console.log(arr)

        });

    });

});

With that code, I get 2 seperate arrays : [eure] and [bas-rhin].

Here is the question : How can I solve it and get these values in a single array ?
