Ruby comes with a program that will show the results of any Ruby statements you feed it. Playing with Ruby code in interactive sessions like this is a terrific way to learn the language.

We intend to release the latest stable Ruby version (currently Ruby 3.4) every two months following the most recent release. Ruby 3.4.6 is scheduled for September, 3.4.7 for November, and 3.4.8 for January.
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).
Identical regexp can or cannot run in linear time depending on your ruby binary. Neither forward nor backward compatibility is guaranteed about the return value of this method.
Ruby was first developed by Matz (Yukihiro Matsumoto) in 1993, and is now developed as Open Source. It runs on multiple platforms and is used all over the world especially for web development.
Operators In Ruby, operators such as +, are defined as methods on the class. Literals define their methods within the lower level, C language. String class, for example. Ruby objects can define or overload their own implementation for most operators. Here is an example:

In the simplest case, the dumped string contains the original string, enclosed in double-quotes; this example is done in irb (interactive Ruby), which uses method ‘inspect` to render the results:
