Display the name of the month in the date - date

Question

I display a date range in my code, which appears as this: 06-08-2017 - 12-08-2017.
But what I would like to see is this: 06 August - 12 August
I wondered how to do it.
Here is the code I use to display dates:
<script>
$(document).ready(function() {
var startDate;
var endDate;
// configure the bootstrap datepicker
var selectCurrentWeek = function() {
window.setTimeout(function () {
$('#js-datepicker').find('.ui-datepicker-current-day a').addClass('ui-state-active')
}, 1);
}
$('#js-datepicker').datepicker({
//config default
altField: "#datepicker",
closeText: 'Fermer',
prevText: 'Précédent',
nextText: 'Suivant',
currentText: 'Aujourd\'hui',
monthNames: ['Janvier', 'Février', 'Mars', 'Avril', 'Mai', 'Juin', 'Juillet', 'Août', 'Septembre', 'Octobre', 'Novembre', 'Décembre'],
monthNamesShort: ['Janv.', 'Févr.', 'Mars', 'Avril', 'Mai', 'Juin', 'Juil.', 'Août', 'Sept.', 'Oct.', 'Nov.', 'Déc.'],
dayNames: ['Dimanche', 'Lundi', 'Mardi', 'Mercredi', 'Jeudi', 'Vendredi', 'Samedi'],
dayNamesShort: ['Dim.', 'Lun.', 'Mar.', 'Mer.', 'Jeu.', 'Ven.', 'Sam.'],
dayNamesMin: ['D', 'L', 'M', 'M', 'J', 'V', 'S'],
weekHeader: 'Sem.',
dateFormat: 'dd-mm-yy',
firstDay: 1,
showOtherMonths: true,
selectOtherMonths: true,
onSelect: function(date,obj){
var daty = $(this).datepicker('getDate');
console.log(daty);
startDate = new Date(daty.getFullYear(), daty.getMonth(), daty.getDate() - daty.getDay());
endDate = new Date(daty.getFullYear(), daty.getMonth(), daty.getDate() - daty.getDay() + 6);
var dateFormat = obj.settings.dateFormat || $.datepicker._defaults.dateFormat;
$('#startDate').text($.datepicker.formatDate( dateFormat, startDate, obj.settings ));
$('#endDate').text($.datepicker.formatDate( dateFormat, endDate, obj.settings ));
selectCurrentWeek();
date = $.datepicker.formatDate('dd-mm-yy', daty);
console.log(date);
$('#date_input').val(date);
}
});
});
</script>
Thank you

Try this :
dateFormat: 'dd-MMMM',

A good library for date format is
http://momentjs.com
From the documentation
moment().format('MMMM Do YYYY, h:mm:ss a'); // August 13th 2017, 8:26:44
