LZX is a prototype-based language: any attribute that can be attached to a class definition, can be attached to an instance of that class instead. This is handy in UI programming, where there are a number of objects with one-off behaviors. It’s also handy in prototyping and incremental program development, where it creates the possibility for a novel kind of refactoring.
The following two XML documents are complete LZX applications . Each defines a view named myview, that contains a method named f. Evaluating myview.f() in either application will result in 100.
