What is the cleanest way to use anonymous functions?

Question

I started using Javascript a lot more, and as a result I write things complex enough that organization becomes a problem. However, this question applies to any language that allows you to install functions. Essentially, when should you use an anonymous function over a named global or internal function?

At first I thought it was the coolest feature, but I think I'm overboard. Here is an example I wrote recently, ommiling all decation variables and conventions so you can see the structure.

function printStream() {
  return fold(function (elem, acc) {
    ...
    var comments = (function () {
      return fold(function (comment, out) {
        ...
        return out + ...;
      }, '', elem.comments);
    return acc + ... + comments;
  }, '', data.stream);
}

I realized, although (I think) some beauty is being so compact, it’s probably not a good idea to do it the same way you wouldn’t want tons of code in a double loop,
