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 love Ruby for the joy it brings me. Been using it professionally for about 7 years, mostly for glue scripting things. Dabbled a little with Rails.

Ruby is my favourite programming language, and I use many ideas from Ruby in other languages. I also like teaching, Linux, and Free Software :)

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!

(He/him pronouns). I've been a Ruby developer for a couple of years (since 2016ish), and I've been helped along immensely by friends and the community--I'm looking forward to paying that back! When I'm not working with code, I'm probably playing or making tabletop RPGs.
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 :)
