    It would be better to say that JavaScript is the new C64 BASIC. It's just as fast, efficient and fun to debug as any old interpreter and allows any {place insulting word of choice here] who was too dumb to understand object orientation or get used to data types to freely create programing horrors.

      Wash your keyboard out with SOAP! I quite like Assembly code...

      The only instant messaging I do involves my middle finger. English doesn't borrow from other languages. English follows other languages down dark alleys, knocks them over and goes through their pockets for loose grammar.

        Just guessing, but I think he has started a Javascript maintenance project. His is the normal reaction as far as I can see...either that or he's getting ready to flood "The Weird and The Wonderful" with examples of "how to do it if you are terminally brain dead". Again, that is a perfectly normal reaction to a Javascript maintenance project! ;)

            Well, it is a scripting language, after all: the one having even the very name misleading. :-D

                  Okay, BASIC I'll go for, but don't impugn Assembly. It takes far more knowledge of hardware, and programming skill, to build a useful program using Assembly than any of the modern languages. And yes, sometimes it has to be done...

                        Ahh, good morning (at leat it is early morning here). I got this drivel from here[^]. While I don't enjoy JavaScript very much, I still have some assembly which I occasionally work on. The code I have posted is used to draw a bitmap patten at any screen coordinates. I use it for text output, but also can be used to draw sprites in a game. That's why ther also collison detection. :)

                          In the UK they are planning plain packaging on cigarette packets - just think of all the extra space for sketching designs such as these.

                                It would be better to say that JavaScript is the new C64 BASIC. It's just as fast, efficient and fun to debug as any old interpreter and allows any {place insulting word of choice here] who was too dumb to understand object orientation or get used to data types to freely create programing horrors.

                                I believe that code block is not properly closed. I don't think you would want to debug that kind of error in a Javascript file...

                                This isn't a signature

                                    Something used in Medieval times (My sophomore year of college) to make inexpensive copies of plans. Huge sheets of paper were used to create drawings of a design.
