Add defer attribute to the <script>.

The script is downloaded in background. And the script is executed once the browser is free after all the HTML document has been parsed.

<script type="text/javascript" id="foo" src="https://flaviocopes.com/javascript-async-defer/" defer></script>

Edit: The script is still executed before the DOMContentLoaded, but after DOM parsing.

This is not an accurate answer, because defer download the script parallelly and run after the dom is parsed and before `DOMContentLoaded` event. Browser is free when everything is done in the background and dom parsed and all scripts loaded and executed. – DecPK Jul 13 '21 at 11:45
