Ruby (programming language)
Ruby has been described as a multi-paradigm programming language: it allows procedural programming (defining functions/variables outside classes makes them part of the root, 'self' Object), with object orientation (everything is an object) or functional programming (it has anonymous functions, closures, and continuations; statements all have values, and functions return the last evaluation). It has support for introspection, reflection and metaprogramming, as well as support for interpreter-based threads. Ruby features dynamic typing, and supports parametric polymorphism.
Rainbow Ruby
At Ruby's house, a small event related to the main plot of each episode occurs, before a red jewellery on the chest of Choco, Ruby's Teddy bear, flashes with a melody. Ruby then takes Choco to her room, and the two 'transport' themselves to the Rainbow Village. There, Ruby hears an explanation from Ling Ling, the mayor of Rainbow Village, and transforms herself using her Rainbow Roller into an appropriate clothing to solve problems. Each episode concludes, back home, with another small event.
The series is distributed as 52 single episodes and as 26 "double feature" episodes. The airings on Family Jr. in Canada are shown in the form of the latter.
