On February 23, 1993, Ruby was born - a dynamic, reflective, interpreted high-level programming language. The language has an operating system-independent implementation of multithreading, strong dynamic typing, a garbage collector, and many other features. In terms of syntax features, it is close to the Perl and Eiffel languages, and in terms of its object-oriented approach, it is close to Smalltalk.
Also some features of the language are taken from Python, Lisp, Dylan and Clu. The cross-platform implementation of the language interpreter is completely free.
