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 its expressiveness, readability and the awesome community. I learnt a lot of good practices in Ruby while solving exercises on exercism and later started using it to mentor people in my workplace. Now I am really excited to do it on a wider scale!

I've been writing code professionally for 10 years. In the last 5 years, Ruby has been my main language. I think Ruby is a great language and I'd love to help other people get into it :-)

I got introduced to Ruby through writing Cucumber tests for a web app. I got addicted to using ruby as I wrote it more and more - it's truly a fun language to write. I use it both for OSS projects and for tooling at work.

Ruby caught my attention due to its idiomatic constructs and powerful metaprogramming capabilities. I've been working with ruby for half a decade and am trully in love with how elegant the code is. I would very much like to evangelize and enfuse in others this passion for ruby.

Learning Ruby was the turning point for me as a developer. Not only is Ruby a beautiful and extremely productive language, but I can say with certainty that if you are a beginner or intermediate developer that learning Ruby will significantly improve your code and workflow in all languages.

I've been writing Ruby professionally for more than ten years. In 2017 I developed and ran an apprenticeship program where we practiced Ruby exercises on Exercism every day.
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 :)
