Computer Programming using GNU Smalltalk tries a different approach for teaching introductory computer programming than most other books by choosing Smalltalk as the programming language. A language which is mature and powerful yet not as widely used as some other popular alternative programming languages out there, waiting for its discoverers. The book aims computer users who have not done any computer programming before or curious programmers who want to learn Smalltalk programming language which is probably one of the influencers of the programming language they are currently using.
Split into two parts, the first part (the Science of SmallTalk) covers the important technical background for programmers and managers; while the second part (the Art of SmallTalk) introduces some of the basic philosophy of SmallTalk. It includes a step-by-step guide taking readers through the basics--right up to designing, coding, and debugging their own programs.
