Ruby is a language in text used to tell machines what to do - a programming language. Ruby was created in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.

It looks like the English language, like the language you are reading now. It has more qualities:

  • Terse. Short, but still easy to understand.
  • Dynamic. Easy to change, any time and any where.
  • Duck typing. If you think you understand it, you probably understand it.

Many programmers like it because the creator tried to make it easy and nice to use.[10]

Example[change | change source]

An example Hello World program in Ruby:

puts "Hello World!"
