And a step further into the past, no need for a lambda - I find this clearer:

  function doWork() {
    function calcX() {
      if (foo()) return f();
      if (bar()) return g();
      return h();
    }

    return calcX() * 10;
  }

Where "calc" can be "gen[erate]" or "find" or at least more descriptive.
