Implement javascript inside body, error: jQuery is not defined

In Drupal 7, I had js-output template.

I define the template output as javascript. This is used for our front end person that can easily input javascript without touching backend.

<script> <?php if(isset($content['field_custom_javascript'])) print $content['field_custom_javascript']['#items'][0]['value']; ?> </script> 

In Drupal 8, I am trying to do the same thing by define twig file:

{% if content.field_custom_javascript is not empty %} <script>     {{ content.field_custom_javascript }} </script> {% endif %} 

But when I put js in the customize_js_output field, as the following:

(function ($, Drupal) {  $( document ).ready(function() {     console.log( "ready!" );  }); })(jQuery, Drupal); 


 $( document ).ready(function() {         console.log( "ready!" );   }); 

Have jQuery is not defined or $ is not defined error. Got all of jQuery libraries load correct in the footer.

My question: Is this a good way to do it? If not, do you have any suggestions?

If i only want to write js inside my body field in the source or even php filter as content editor, can I do it?
