In this course my goal was to give you a good understanding of the HTML5 messaging application programming interface. I've covered how the API works, how to setup the event handlers, how to send and receive data, and how to handle errors in your messaging applications. Using these features, you should be able to implement cross-origin scripting for your own applications. As with most of the HTML5 application technologies, the specifications for the HTML5 messaging API remains in flux. I suggest that you keep up with these changes in order to make sure that your code works with current and future browsers.
