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 have worked primarily in Ruby for a few years now. Its ease of learning and versatility make it both a great language to start with and to use in the real world.

In coding, ruby was my first love. I've been writing it professionally for >4 years and love how expressive it can be. Have you seen the ruby poetry?

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.

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