Read “Practical Object-Oriented Design in Ruby” 2nd edition

Finished to read and practiced Practical Object-Oriented Design in Ruby 2nd . The book was 2nd version which has been published 1sr, Sep 2018.

The book addresses Ruby mainly in code level, but we can learn OOP styled programming, thinking from the book for non-Ruby engineers.

My ordinal motivation was learning programming languages, especially OOP, in English, again. I’ve learned some programming languages in English first since they have no Japanese resources then while I learned OOP in Japanese before.

I also would have liked to make my knowledge shape up again about OOP.

Thus, I started leading the book.
