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 and have been using it professionally for more than 10 years. I also have been spending time on how to write a easy to read and easy to extend Ruby code. I am new to mentoring and a non-native English speaker. Please excuse my brevity. If my feedback to you is rude, first I am sorry and second it was not my intention. Please do reach out to me, it gives me an opportunity to learn through feedback for mentoring.

Ruby is the first language I've developed in professionally, I love it for it's readability and how it was developed with the intention to bring joy to those who write it.

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!

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.

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 :)
