    After the body closing tag, only comments and closing tags of html elements are allowed to be added.

    You can confirm via Specification or Validator.

    Browsers may perform error recovery, and the HTML specification even describes how to recover in this case, but you should never rely on this.

    With the advent of the defer attribute, we can place script inside and get this benefit while also having the browser download the HTML in parallel to Improve performance.

    It will not validate outside of the <body> or <head> tags. It also doesn't make much of a difference unless you're doing DOM manipulation before the element is fully loaded which might break IE - put it before closing the . 

    <html>
  ....
  <body>
     ....
     <script type="text/javascript" src="theJs.js"></script>
  </body>
</html>
