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.

After years of light web development in the financial industry, I changed course to follow my passion for software development. I love working with Ruby and Javascript and am currently building my knowledge around Elixir, Java, React, and Angular.

What can I say? I love Ruby. And I believe it is one of the best languages for anyone to start out with. The syntax is beautiful, and you'll have a lot of support from the community (and me). I've been using Ruby for about 4 years now, and it is one of the reasons I still enjoy coding in my spare time.

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 :)
