What is Ruby?
Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby is a scripting language that combines the best elements of other popular languages such as Perl, Smalltalk, Eiffel, Ada, and Lisp.

Ruby is an object-oriented interpreted scripting language created by Yukihiro Matsumoto. Since the mid 1990s, it has grown in popularity in Japan and has gained recent attention as the language behind the Rails framework. You can use the language for a striking variety of functions—from basic scripting to creating Windows applications to developing Web applications. You can start using Rails without extensive knowledge of the language; the Rails framework generates the fundamental classes needed for the Web application and uses reflection to perform object-relational mapping to the database. What is Rails? Rails is a Web application and persistence framework created by David Heinemeier Hansson. It includes the infrastructure you need to create database-backed Web applications that use the Model-View-Control (MVC) pattern. Rails has gained attention as a development framework that lets you rapidly create full-featured database-backed Web applications. What is the Model-View-Controller P
Ruby is a very high level, fully OO programming language. Indeed, Ruby is one of the relatively few pure OO languages. Yet despite its conceptual simplicity, Ruby is still a powerful and practical “industrial strength” development language. Ruby selectively integrates many good ideas taken from Perl, Python, Smalltalk, Eiffel, ADA, CLU, and LISP. Ruby combines these ideas in a natural, well-coordinated system that embodies the principles of least effort and least surprise to a substantially greater extent than most comparable languages — i.e., you get more bang for your buck, and what you write is more likely to give you what you expected to get. Ruby is thus a relatively easy to learn, easy to read, and easy to maintain language; yet it is very powerful and sophisticated. In addition to common OO features, Ruby also has threads, singleton methods, mixins, fully integrated closures and iterators, plus proper meta-classes. Ruby has a true mark-and-sweep garbage collector, which makes co
