[SOLVED]Date format

Hi

im trying to add the content of a date field to subject but i need to change the format 

this is my script

var nom=$CS.getValue("ServiceReq_User_UDF_CHAR9");
var prenom=$CS.getValue("ServiceReq_User_UDF_CHAR8");
var date=$CS.getValue("ServiceReq_User_UDF_DATE1"); 
var y="Nouvel Employé / New Hire: ";
$CS.setValue("SUBJECT",y + prenom + " " + nom + " " + date); 

date will show in format Tue Jun 18 2019 12:16:00 GMT-0400 (heure d’été de l’Est)

i would like to only show (Jun 18 2019)

how could i do this ?
