Ruby is a programming language from Japan that focuses on Developer Happiness.

Ruby powers many of the web applications that you know and love, such as Basecamp, Shopify, GitHub, HEY, and many more. All these apps were built using Ruby on Rails, a web application framework that’s written in Ruby.

Most likely, you’re interested in learning Ruby as you want to try Rails. If that’s the case, you’re at the correct place.

In this series of posts, I will teach you Ruby and show how you can build simple web applications using Ruby. If you’re new to the language, or have never programmed before, this will be your gentle introduction to Ruby.

I will teach you just enough Ruby so you can understand and build your own Rails applications. Once you finish this guide, which shouldn’t take long, I will teach you Rails.

Sounds interesting? Let’s get started. We’ve got a lot of ground to cover.
