What’s the difference between a page that does nothing and a page that seems to be always dancing? One word: javascript. If you want your pages to be dynamic and interactive, you need a bit of behind-the-scenes javascript to make it so. “But,” I hear you object, “HTML isn’t that hard to learn. javascript is a programming language, for crying out loud!” I hear you. It’s true that anyone can learn HTML as long as they start with the basic tags, examine lots of examples of how they work, and slowly work their way up to more complex pages. It’s just a matter of creating a solid foundation and then building on it.
I’m convinced that javascript can be approached in much the same way. I’m certainly not going to tell you that javascript is as easy to learn as HTML. That would be a bald-faced lie. However, I will tell you that there is nothing inherently difficult about javascript. I believe that if you begin with the basic syntax and rules, study tons of examples to learn how they work, and then slowly build up to more complex scripts, you can learn javascript programming. I predict here and now that by the time you finish this book, you’ll even be a little bit amazed at yourself and at what you can do.
