I hope Ruby helps every programmer be productive, enjoy programming, and be happy. That is the primary purpose of Ruby language.
— YUKIHIRO MATSUMOTO, CREATOR OF RUBY
Ruby is a server-side language created by Yukihiro “Matz” Matsumoto, a developer who was looking for an easy-to-use scripting language. Matsumoto had experience programming in other languages like Perl and Python, and, unsatisfied with both, created Ruby. When designing Ruby, Matsumoto’s explicit goal was to “make programmers happy”, and he created the language so programmers could easily learn it and use it. It worked. Today Ruby, and particularly Ruby working with a Ruby framework called Rails, is the most popular way for startups and companies to quickly create prototypes and launch websites on the Internet.
In this chapter, you learn Ruby basics, including its design philosophy; how to write Ruby code to perform basic tasks; and steps to create your first Ruby program.
