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 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!

In coding, ruby was my first love. I've been writing it professionally for >4 years and love how expressive it can be. Have you seen the ruby poetry?

I love Ruby for its beauty and consistency. I've been happily working with it for 10+ years and don't see myself stopping any time soon. Mentoring has been a great way to help the community while reinforcing my skills and knowledge in programming.

I'm a Ruby on Rails developer and I fell in love with Ruby many years ago, probably because it is made for developer happiness and productivity. Happy to help you learning this nice language!
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 :)
