Normally, the JavaScript code is loaded by a <script> tag in the HTML, and it runs immediately after it is loaded.

No I mean, in the video how does Dave make the script load when the page loads. Either a event happens or something get called?

I think we are talking about the same thing. When the page loads, the HTML contains one or more <script> tags that identify the JavaScript modules. As each tag is encountered during loading, the script code is loaded and immediately executed. This is an automatic browser function and does not require anything special in the code.
