About Ruby

Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.

Ruby was created as a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

He has often said that he is "trying to make Ruby natural, not simple," in a way that mirrors life.

Building on this, he adds: "Ruby is simple in appearance, but is very complex inside, just like our human body."

You can read more about the Ruby language on its site.

Key Features of Ruby

Developer happiness

Ruby puts developer-happiness first. It has an elegant syntax that is natural to read and write.

Metaprogramming magic

Ruby code can write and invoke Ruby code.

Garbage Collection

Garbage collection done via mark and sweep, stays out of your way.

Large standard library

Ruby's standard library provides a wealth of classes utilities for common tasks.

Flexible package manager

Packages (gems) can be centrally managed, but can also include custom or private gem stores.

Strong, dynamic typing

Ruby is strong and dynamically typed and supports 'Duck Typing'. Everything in Ruby is an object
