Firstly, Ruby is a very intuitive and clean programming language. This makes learning Ruby a less challenging task than learning some other languages. Ruby is also a great general purpose language. It can be used to write scripts in the same way you might you use Perl, and it can be used to create full scale, standalone GUI based applications. Ruby's usefulness doesn't end there however. Ruby is also great for serving web pages, generating dynamic web page content and excels at database access tasks.

And, of course , being an interpreted language means that Ruby is portable. Once an application has bene been developed in Ruby it will run equally well on Ruby supported platforms such as Linux, UNIX, Windows and MacOS X.
