</body>tag of your html document. Don't forget to replace
Once the initial webpage has finished loading, the above script will begin downloading and executing
<script>tags to the bottom of your page. This method however is sub-optimal as the browser will continue to show a busy indicator until the last JS has completely finished being parsed. In some cases, users may not interact with a page until the busy indicator shows that the page is completely loaded, therefore resulting in longer load times and a substandard user experience.
