Ruby is a general purpose, scripting, structured, flexible, fully object-oriented programming language with a focus on simplicity and productivity. Ruby is a very conservative language. It’s equipped with very carefully chosen features that have been fully tested.
Ruby possesses a high portability running a large number of platforms including Linux, Windows, Mac OS X, Cygwin, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, Tru64 UNIX, and HP-UX. At the time of publication, the TIOBE Programming Community index ranks Ruby in 11th place.
Ruby’s popularity was enhanced by the Ruby on Rails framework, a full-stack web framework which has been used to create many popular applications including Basecamp, GitHub, Shopify, Airbnb, Twitch, SoundCloud, Hulu, Zendesk, Square, and Highrise.
Here’s our recommended tutorials to learn Ruby. If you’re looking for free Ruby programming books, check here.
1. The Definitive Ruby Tutorial For Complete Beginners by RubyGuides
Learn everything you need to know to get started learning this fun programming language so you can create your own Ruby programs and do amazing things!
2. Learn Ruby by C42 Engineering
Free, interactive tutorials to help you discover Ruby idioms, in your browser.
3. The Ruby Style Guide by RuboCop Headquarters
This Ruby style guide recommends best practices so that real-world Ruby programmers can write code that can be maintained by other real-world Ruby programmers. A style guide that reflects real-world usage gets used, while a style guide that holds to an ideal that has been rejected by the people it is supposed to help risks not getting used at all – no matter how good it is.
4. Ruby in Twenty Minutes by the Ruby Community
This is a small Ruby tutorial that should take no more than 20 minutes to complete.
5. Learn Ruby by Edgecase
The Koans walk you along the path to enlightenment in order to learn Ruby. The goal is to learn the Ruby language, syntax, structure, and some common functions and libraries. It also teaches you culture.
6. Ruby Study Notes by Satish Talim
The Ruby Study Notes is a step-by-step tutorial to programming in Ruby and you can follow it page by page, reading the text and running the sample programs. There are no large applications here – just small, self-contained sample programs.
