Ruby 3.2.2

What is Ruby?

Ruby is a simple and powerful object-oriented programming language, created by Yukihiro Matsumoto (who goes by the handle “Matz” in this document and on the mailing lists).

Like Perl, Ruby is good at text processing. Like Smalltalk, everything in Ruby is an object, and Ruby has blocks, iterators, meta-classes and other good stuff.

You can use Ruby to write servers, experiment with prototypes, and for everyday programming tasks. As a fully-integrated object-oriented language, Ruby scales well.

Ruby features:

• Simple syntax,
• Basic OO features (classes, methods, objects, and so on),
• Special OO features (mixins, singleton methods, renaming, and so on),
• Operator overloading,
• Exception handling,
• Iterators and closures,
• Garbage collection,
• Dynamic loading (depending on the architecture),
• High transportability (runs on various Unices, Windows, DOS, macOS, OS/2, Amiga, and so on).
