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.

Ruby literally changed my programming career. It made me know that programming can be so much enjoyable. Hope to share more about this joy on Exercism.

I love Ruby because of it's developer friendliness over everything and the speed of which you can just get going with tasks.

Hi, there! I've been working with Ruby since 2015 and am a big fan of the community and mentorship. My previous career was in Music/Education and I find those skills have helped me be a better teammate and teacher. I look forward to working with you!

Mohnish is a programmer who cares about - programming as a craft, mentorship, diversity, inclusiveness and empathy. Away from work, he enjoys contributing to open source, blogging, and has even organized Ruby user group meetups in the past. He's also learning more of Elixir whenever he gets an opportunity.
Fun. Challenging. Interesting
