Ruby was created in 1993 by Yukihiro Matsumoto to balance functional and imperative programming. It is a dynamic, reflective object-oriented scripting language that is simple, powerful, and flexible. Key features include being highly readable, having a interactive shell, embracing object-oriented programming, and having a large ecosystem including Ruby on Rails.
![Good point of Ruby
Reduce code
• Java
public class HelloWorld {
public static void main(String args[]) {
System.out.println(“Hello World”);
}
}
• Ruby
puts “Hellow World”](https://image.slidesharecdn.com/whyruby-121106013931-phpapp02/85/Why-ruby-5-320.jpg)

- 4. What is Ruby? - Ruby is a dynamic, reflective, general-purpose object-oriented programming language that combines syntax inspired by Perl with Smalltalk-like features. - Interpreted Script Language - Ruby was first designed and developed in the mid-1990s by Yukihiro „Matz‟ Matsumoto in Japan. - The standard 1.8.7 implementation is written in C.
- 5. Good point of Ruby Reduce code • Java public class HelloWorld { public static void main(String args[]) { System.out.println(“Hello World”); } } • Ruby puts “Hellow World”
- 6. • Communities • Code is Human-Readable: The code was designed from the start to be human- readable and this means that non-programmer can have a very easy to understand what a program is designed to do. • Ruby on Rails: A Model-View-Controller framework for creating database-driven websites in Ruby. Rails is build on simple concepts. (http://guides.rubyonrails.org/)
- 7. • RubyGems: A package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries (in a self- contained format called a “gem”), a tool designed to easily manage the installation of gems, and a server for distributing them. (http://rubygems.org/) • Command-line: The interactive Ruby shell is a unique feature that allows developers to maintain and experiment with commands. There is no need to write webpages and check their functionality in a browser. • Object-Oriented-Programming (OOP): Object-Oriented-Programming is a necessity for clean and maintainable code. However, In Ruby, everything is an object . Ex: 5.class #=> Fixnum “Ruby” #=>.class String nil.class #=> NilClass Fixnum.class #=> Class
- 8. • Ruby is free • Encourage testing - Test::Unit builds in into standard library - Other tools: Rspec, … Ruby online resources: - Try Ruby - http://tryruby.org - Hackety Hack - http://hackety.com/ - Ruby Monk – http://rubymonk.com/ - New Boston Videos - http://thenewboston.org/list.php?cat=50 - Ruby Notes - http://rubylearning.com/satishtalim/tutorial.html - Ruby Documentation - http://www.ruby-lang.org/en/ & http://ruby-doc.org/ - Ruby Conference Videos - http://confreaks.com/events - Ruby Koans - http://koans.heroku.com/ - Ruby Regex – http://rubular.com/ - Ruby Online Quiz/ Exam - http://rexaminator.com/ - Nettuts+ Ruby for Newbies Sessions – http://net.tutsplus.com/sessions/ruby-for-newbies
