		wahnfrieden on Jan 9, 2011 \| parent \| context \| favorite \| on: Ie7-js Another JS bug in older versions of IE (6 for sure, not sure about later ones) occurs when you end an array or hash with a comma after the last element, e.g. {foo: bar,}

IIRC, this is actually invalid Javascript syntax that Chrome/Firefox/Safari choose to ignore.

JSLint picks it up:

  Error:
  Problem at line 1 character 22: Extra comma.

  var x = { foo : "bar", };
