    You're right, typeof new Function() === "function". *trim*

    Normal people punch things when they get angry!

    What on earth does it actually do?

    Dal: I explained it in an earlier post (the interesting bit, anyway: it also prints out various animal noises, but... no-one cares about that). Trinithis also linked to a book (an excellent book, by the way, which I highly recommend) which covers this amongst other topics.

    Eh, various things.

    Was there a woman involved? I guess I deserved that short answer in trade for mine. Well you certainly haven't given us any reason here not to tick you off.

    I especially liked (and I may be seeing the code wrong, so I guess I should say, "what looks to me like") the use of an anonymous function as an object in the global scope. But I will be scratching my head for awhile over exactly why. I thought that there wasn't much point in having an anonymous function other than getting all but its execution out of the global scope.

    You are indeed seeing that incorrectly, I believe. The function is called. However, there are some situations in which the pattern you describe is useful; I use it in my 'DOM' toolkit, something like this:
    Code:
    var Dom = (function() {
      var r = function(s) {
        // CSS selector stuff
      };
    
      r.byName = function(s) {
        return document.getElementsByName(s);
      };
    
      return r;
    })();
    Which allows code like:
    Code:
    var someEl         = Dom("#some-id"),
        someOtherEls   = Dom.byName("and-a-name"),
        andSomeMoreEls = Dom(".some-class");
    ... where the most useful function is more easily accessible (at the cost of being named less descriptively).

    Fantastic stuff, Im sure I may even use this one day but I have no need for it at the moment. Im a noob at javascript, only 4 months experience. Thanks to C/C++ Im doing fine but functions like even the one above is a little too OOP for getting things done.

    Well, you'll never have a need for it. It's a convenience. Rather than:
    Code:
    function foo(arg) {
      if (typeof arg === "string") {
        bar();
      } else if (typeof arg === "number") {
        baz();
      } else {
        quux();
      }
    }
    You would:
    Code:
    var foo = Generic.create(quux);
    foo.specialise(['string'], bar);
    foo.specialise(['number'], baz);
    It's particularly interesting because it's a convenience that can be used to implement a form of object orientation that's much more powerful than Java's or C++'s.
