Включить Javascript

Я хочу включить в свое представление некоторый код javascript, но понятия не имею, как это сделать. Я безуспешно искал это, нет четких указаний на это.

Я хочу вставить несколько выбираемых таблиц с помощью начальной загрузки, ссылка находится на https://datatables.net/extensions/select/examples/styling/bootstrap4.html.

javascript это

  $(document).ready(function() {
      $('#example').DataTable( {
          select: true
      } );
  } );    

таблица это

<table id = "example" class = "table table-striped table-bordered" style = "width:100%">
    <thead>
        <tr>
            <th>Name</th>
            <th>Position</th>
            <th>Office</th>
            <th>Age</th>
            <th>Start date</th>
            <th>Salary</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>Tiger Nixon</td>
            <td>System Architect</td>
            <td>Edinburgh</td>
            <td>61</td>
            <td>2011/04/25</td>
            <td>$320,800</td>
        </tr>
...

Говорят, что я должен включить эти библиотеки javascript

https://code.jquery.com/jquery-3.3.1.js
https://cdn.datatables.net/1.10.19/js/jquery.dataTables.min.js
https://cdn.datatables.net/1.10.19/js/dataTables.bootstrap4.min.js
https://cdn.datatables.net/select/1.2.7/js/dataTables.select.min.js

Но где мне это делать ?? нет html головы ...

Я попробовал типичный

<script type = "text/javascript">
  $(document).ready(function() {
      $('#example').DataTable( {
          select: true
      } );
  } );    

  document.write(5 + 6);
</script>

Как запустить код? Я полагаю, что это делается при загрузке таблицы со ссылкой на #example ...

Хорошо, я попробовал кое-что. Конечно, я не хочу, чтобы вы решали мою проблему, но ничего не помогло. Включаю почти полный код. Он должен работать, как в примере из верхней ссылки. Я не знаю, является ли тот факт, что laravel 5.5 действительно работает с bootstrap 4, а не с включенным, является фактором, на самом деле я не знаю, работает ли он по умолчанию с jquery ...
