JavaScript in HTML

External Script

<script src="path/to/javascript/file.js" type="text/javascript" > </script>

Script within HTML document

<script type="text/javascript">
 /*
   JavaScript code as content of script element
 */
</script>

"Inline" scripts as values of event attributes (Avoid!)

<a href="#" 
  onclick="javascript:void(window.resizeTo(1024,768))">
  Size Window to 1024 x 768
</a>
