Why ruby?

Ruby is a dynamic, object-oriented programming language created in 1993 by Yukihiro Matsumoto. It aims to make programmers happy and productive by providing a human-readable syntax and allowing ideas to be expressed through code. Ruby on Rails is a popular web framework built on Ruby that uses a model-view-controller pattern to create database-driven websites in a simple way. Ruby features like interactive shells, object-oriented programming, and built-in testing tools help encourage clean and maintainable code.

- 4. The Ruby Language “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 Matz in Japan.” “The standard 1.8.7 implementation is written in C. “ •be productive •to enjoy programming •and be happy

- 7. Code is Human-Readable “The code was designed from the start to be human-readable and this mean that non-programmer can have a very easy to understand what a program is designed to do”. 3.Times { print “Ho!” }

- 10. Ruby Gems Problem: • Hard to find libraries? Application Database Interface Mailer Web Services Logger Solution: • Package Version & Dependency Management • Package Delivery • Package Documentation Management »gem install rails –include dependencies
- 11. Command-line “The interactive Ruby sheel is a unique feature that allows developers to maintain and experiment with commands-line. There is no need to write webpages and check their functionality in browser.”
- 12. Object-Oriented-Programming “Object-Oriented-Programming is a necessity for clean and maintainable code. However, In Ruby, everything is an object.”
- 13. Encourage Testing Test::Unit builds in into standard library Other tools Rspec, MiniTest, ...
