The host environment
With or without a browser?
A little heads-up to the purists out there: You might notice that even though we keep the browser out of the equation during the first part of the tutorial, I will be using a couple of functions which could be considered browser related. An example of this is the alert() function, which will show a simple message box in the browser. I use it because it's simple and easy to understand in the examples we use in this tutorial, and because it produces a result which can be seen when reading the tutorial in a webbrowser and running the examples directly from the website.
