 {
  $.ajax({
   url:"fetch.php",
   method:"POST",
   data:{view:view},
   dataType:"json",
   success:function(data)
   {
    $('.dropdown-menu').html(data.notification);
    if(data.unseen_notification > 0)
    {
     $('.count').html(data.unseen_notification);
    }
   }
  });
 }

DreaemWeaver is not using ES6 (which introduced default values for parameters) by default. But you can set this behavior in the settings. Just take a look at it.

JavaScript before ES6 doesn't support default values for parameters. But you can rewrite it to if you don't wnat to change the settings (which would be recommend):

function load_unseen_notification(view) {
  view = view || ''; // if view is defined, use the value. If not set view to an empty string.
