If you view http://www.visitorjs.com/visitor.js http://www.visitorjs.com/visitor.js, that JS already has your data concatenated with the script. Why is this?

  Because it's generated server side.

    What are the advantages of concatenating the data with the JS vs making a request? Only page load time?

      You can't make a cross-domain ajax request, so all of the data needs to be included with the JS.

        I had never thought of doing this. Its a great idea. How widespread is this technique?

          Quite, it's mostly used as JSONP. See http://en.wikipedia.org/wiki/JSONP http://en.wikipedia.org/wiki/JSONP
