Introduction

When I first came across Ruby, it was on the GitHub blog. The GitHub blog is built with Jekyll a static site generator. This Jekyll is made of ruby. So I became interested in the language Ruby, and I want to find out about it.

Ruby; A programmer's best friend

• Ruby is developed programming language by Matsumoto Yukihiro In 1995
• Similar to Python
• Script language(: A language used to control existing software. Ex; JavaScript, Python...)
• All APIs are written in Japanese.

I thought, 'Why are there so many places in Japan that use ruby?', and this seems to be the reason.

Ruby on Rails

• Web framework using Ruby(Ex; JavaScript - Node.js, Swift - Vapor)
• Open source
• So easy to learn
• Pure object-oriented language
• Meta programmable
• This framework is what made Ruby famous
