This is common in Javascript, but still makes me cry. I would rather
see something like this:

  function main() {
      make_ajax_call(url, ajax_call);
  }

  function ajax_call() {
    // 10 lines of code
  }

This way ajax_call can be in a different file and can be used in other
code without duplication.

I think you are refactoring in reverse.
