Recently Laszlo, an XML platform for rich internet applications went open source. This platform applies an architecture that is similar to XUL and XAML to accomplish programming on the browser. Laszlo uses "Flash" as its execution platform resulting in unsurpassed browser compatibility, while requiring no Flash executables or license for development. Laszlo offers a fairly matured platform to exercise this architecture.

As Bill Grosso has already covered the basics of this platform on, in this article I will focus on some of language fundamentals that will come handy when you are experimenting with Laszlo.

Although the documentation on Laszlo site is quite good, it will take a while to cover all the variations even to get your footing. This article exposes some of the language aspects of Laszlo even for a casual reader.
