I came across an idea as assigning an id to the <script> element and
passing the arguments as data-* attributes. The resulting <script> tag would
look something like this:
<script id="helper" data-name="helper" src="helper.js"></script>
The script could then use the id to programmatically locate itself and parse
the arguments. Given the previous <script> tag, the name could be retrieved
like this:
var name = document.getElementById("helper").getAttribute("data-name");
We get output name = helper
