Ortelius can make documentation from both javascript and actionscript. Its is the same program you use. The only different is whether you start a javascript project or a actionscript project.

Javadoc tags in your javascript
Ortelius uses javadoc tags in the code to extract information about the different property or functions. The information you write in theese tags is extracted by the generator and put in to a html documentation of your javascrpt files.
