JavaScript for Automation (JXA) Anyone?

I can't seem to find any more-or-less "official" place to discuss JavaScript for Automation (JXA). I've managed to develop some level of skill at JXA, although I have a long way to go.

What I want to know is, is there some place I can go to both contribute my knowledge, and get some answers?

Here's one example of a situation where I have no idea where to go to for answers:

Let's say I have an object that I want to turn into a plist XML string. I use code like this:

function serializeObjectToXmlPlist(obj) {
     var data = $.NSPropertyListSerialization
          .dataWithPropertyListFormatOptionsError(
               $(obj), $.NSPropertyListXMLFormat_v1_0, 0, null);
     var nsString = $.NSString.alloc
          .initWithDataEncoding(data, $.NSUTF8StringEncoding);
     return $(nsString).js;
}

The problem with this code is that if there are any nodes of type "data" (which contain base64-encoded strings), their content does not get serialized to the XML string.

Where do I go to find answers to questions like this?

Thanks.
