How to pass parameters to JavaScript files?
To pass parameters to JavaScript files, we can store data in data attributes.
For instance, we write
<script id="helper" data-name="helper" src="helper.js"></script>
to add a script element with the data-name attribute.
Then we get the value of the data-name attribute with
const name = document.getElementById("helper").getAttribute("data-name");
We call getAttribute with 'data-name' to return the value of the data-name attribute after selecting the script element with getElementById.
