Try this one , you need to use @json()

<script type="text/javascript">
     
       let checkInn =  @json($array);
      // var checkInn = ["10-10-2021","10-10-2021"];
      $('.datepicker').datepicker({
          format: 'mm/dd/yyyy',
          beforeShowDay: function(date){
              dmy = date.getDate()   "-"   (date.getMonth()   1)   "-"   date.getFullYear();
              if(checkInn.indexOf(dmy) != -1){
                  return false;
              }
              else{
                  return true;
              }
          }
      });
    </script>
