Summary
Extending AJAX with Flash creates a very unique user experience that one technology would have trouble producing. By leveraging these technologies to focus on their strong points, the application becomes more modular, which makes it more scalable, leaving room for expansion. Most importantly, it makes the user experience more responsive, which in turn makes it more usable and intuitive to the user. The Flash /JavaScript Integration Kit makes the extension simple by providing a wrapper for direct communication between Flash and JavaScript.
