Hello @MaxAllen

You can add defer tag to execute the script after the HTML has finished parsing instead of javascript blocking the parsing.  
\<script src=“myfile1.js” defer\>\</script\>  
Here’s a reference to how to defer would work :[\<script\> HTML script element - HTML | MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#attr-defer)
