Is it possible to console.log the contents of the loaded third party script from an HTML script tag?

Lets say I am using the turndown Javascript package:

https://github.com/mixmark-io/turndown

and loading it this way in my HTML:

<script src="https://unpkg.com/turndown/dist/turndown.js"></script>

This loads the following:

enter image description here

and makes TurnDown service available to be used as such:

var turndownService = new TurndownService({ headingStyle: 'atx', emDelimiter : '*' });

Is it possible to console.log the entire script which has been loaded by the above script tag? Aka, is it possible to log the following:

var TurndownService = (function () {
  'use strict';

  function extend (destination) { ........

  .....

  return TurndownService;

}());

The reason I need to do this is that I want to pass these third party scripts to a WebView in iOS using webkit handlers.
