About Ruby

class HelloWorld
  def self.hello(name = 'World')
    "Hello, #{name}!"
  end
end

Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.

Ruby was created as a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

He has often said that he is "trying to make Ruby natural, not simple," in a way that mirrors life.

Building on this, he adds: "Ruby is simple in appearance, but is very complex inside, just like our human body."

You can read more about the Ruby language on its site.

I loved the Ruby track

I loved the Ruby track (it is the only one I have finished so far). Solving over 80 different problems seems one of the most exciting ways to learn a language one barely knows. Improving my own solutions for readability and beauty rather than just passing the tests and performance taught me a little about Ruby and programming in general. I also liked comparing my solution to other ones - I could see the problem from other points of view.

Relaxed. Encouraging. Supportive.

I'm a lapsed mechanical engineer and robotocist turned software developer, deeply in love with Ruby (although Elixir is pretty great too). Currently the Application Development Manager @ Yale University.

Working as ruby on rail(RoR)s last 4 years (I recommend to have a look at RoR when learning Ruby). I have total 8+ years in software development. I always believe sharing knowledge is a beautiful concept, exercism is perfect place to learn and share your knowledge.

I love Ruby because it delivers on its promise: programmer happiness. As a programmer, I'm happy when my code is intention revealing, easy to reason about and easy to change. I have used Ruby to build 4 startups over 12 years and I'm not done yet.

I want to work as a ruby developer because Ruby taught me how intersting programing is. I started to study Ruby 6 months ago but I've learned a lot of things from mentor and exercise in Exercism. I want to be like them to support people like me

Ruby is awesome. It's easy to learn, easy to read and yet so powerful. I've learned many programming languages and ruby will always be my favourite one. Besides the ruby community is super nice!

Ruby was the starting point for me learning to program. It still is my go-to-language for web applications and my knowledge made it easier for me to learn new languages I use at work.
Fun. Challenging. Interesting

Ruby has been my go-to language for the past 6 years. I love how readable and intuitive it is. I'm thankful for the opportunity to help others on their journey in any way I can and I'm hoping to become a better mentor in the process :)
