From: www.cc.gatech.edu/~schoedl/projects/NewtonScript/: NewtonScript, developed for the Apple Newton PDA platform, is a prototype-based programming language. Rather than two levels of abstraction, class and object, there is just one, the object. Major design goals of the language were small memory consumption of the created programs and the ability to easily program graphical user interfaces. Both are well met by prototype-based languages. A third design goal, good learnability, was attained by an easy syntax. Though, the author's experience with a class project revealed that some other simplifying features as well as the dynamic typing of the language in conjunction with a bad programming environment make programming and especially debugging of NewtonScript programs difficult.
