How can you generate a javascript array while iterating over your Currentpage children?

My foreach:

@{
        var branches = country.Children.Where("Visible").OrderBy("Name");

         if (branches.Count() > 0)
         {
                 foreach (var branch in branches)
                 {

                      // add entry to the locations array

                 }
         }
}

Desired output to set in my javascript is:

var locations = [
     ['Location 1', 51.50013, -0, 126305],
     ['Location 2', 48.8566667, 2.3509871],
     ['Location 3', 59.9138204, 10.7387413],
     ['Location 4', 41.8954656, 12.4823243]
];

Is must be set in my Script section which is in the same page of the foreach:

@section Scripts {
    <script>
        /* <![CDATA[ */
        jQuery(document).ready(function ($) {
            'use strict';

            var locations = []; // here I need to set the output

            // do something with this array...

        });
        /* ]]> */
    </script>
}
