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 was the starting point for me learning to program. It still is my go-to-language for web applications and my knowledge made it easier for me to learn new languages I use at work.

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 was where I started and is how I fell in love with coding. It's a great language to start off with, so well done on choosing it. I'm very happy to be helping you learn, go you!

I want to work as a ruby developer because Ruby taught me how intersting programing is. I started to study Ruby 6 months ago but I've learned a lot of things from mentor and exercise in Exercism. I want to be like them to support people like me

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 :-)

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 :)
