fullcalendar is not a function while using in Laravel

I am trying to use fullcalendar in my laravel app.

Scripts in webpage source code

    <script src="http://127.0.0.1:8000/js/vendors/moment.js"></script>
    <script src="http://127.0.0.1:8000/js/vendors/jquery.min.js"></script>
    <script src="http://127.0.0.1:8000/js/vendors/fullcalendar.min.js"></script>
    <script src="http://127.0.0.1:8000/js/script.js"></script>
</body>
</html>

Code in script.js

$(function() {
    $('#calendar').fullCalendar({
      editable: true,
      eventLimit: true,
    });
});

I have #calendar div in my page and my console is showing error

Uncaught TypeError: $(...).fullCalendar is not a function
