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'm a recent career changer, having left NHS Accountancy for a coding bootcamp. I'm now in my first year of a Full Stack Developer role, working predominantly with Rails. I've been helped by exercism.io and want to do my bit to keep the Ruby learning track flowing.

I have found Ruby the most fun language to use. I've been using Ruby full-time since 2006 (mostly Rails applications).

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.

I'm a former teacher, now an engineer at Pivotal. I'm passionate about learning new programming languages, and helping others learn.

I started working with Ruby 6 years ago and immediately fell in <3 with its elegance and expressiveness. However, one of the things that (still) appeals to me the most is the incredibly savvy, creative and welcoming community behind it. I'm grateful for the opportunity to be a part of it via this amazing project!
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 :)
