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 will always be dear to me because it lets you say what you need in the way that you want. I use Ruby at work.

What can I say? I love Ruby. And I believe it is one of the best languages for anyone to start out with. The syntax is beautiful, and you'll have a lot of support from the community (and me). I've been using Ruby for about 4 years now, and it is one of the reasons I still enjoy coding in my spare time.

I'm a Ruby on Rails developer who thinks Ruby and the entire ecosystem is glorious. I've had a pull request merged into Rails, and love finding opportunities to contribute to open source.

When I started dabbling with programming in Ruby over 15 years ago, I did not expect it to pay my bills ánd make me happy!
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 :)

Get started with the Ruby track. As with everything on Exercism, it's 100% free!
