JS execution sequence on the HTML page:

1) the first execution in the head label

2) execution in the Body Tag

3) when the onload event is added to the body tag, the corresponding JS is finally executed, that is, when the page is loaded


Note:: When an onload event is added to the body tag, the referenced external JS does not work in the head tag, it can be referenced normally when external JS is referenced inside the body or above
