 JavaScript uses a lot of collections. A collection is an ordered list of objects. You can access a particular element of the collection using either array notation or the item() method. The following script extracts all FONT tags into a collection and computes the font face of the third element (index is 2): 

<SCRIPT LANGUAGE="JavaScript">
<!--
function handleAllTags() {
var arrayOfFonts;
  if (document.all) {
    arrayOfFonts = document.all.tags("font");
  }
  else if (document.getElementById) {
    arrayOfFonts = document.getElementsByTagName("font");
  }
  else {
    document.write("Unrecognized Browser Detected");
  }
  var out = 'arrayOfFonts[2].face = ' + arrayOfFonts[2].face + 
  '; arrayOfFonts.item(2).face = ' + arrayOfFonts.item(2).face;
  document.write(out);
}
// -->
</SCRIPT>
