Json first object is a *, how to get it?

If I run:

$("#results ul").append(data.parse.langlinks.map(function(val){ return "<li>" + val.lang + "</li>" }));

I get all correct values of lang but I need to get the first object and it doesn't have a verbal naming but it has

*

So when I try to access it like val.* I get:

Uncaught SyntaxError: Unexpected token *
