From the Ruby Introduction Language Specification for Professionals to Test-Driven Development and Debugging Techniques Hobby

Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.

This is a manual where you can learn Ruby grammar with example code and experience the flow of programming with examples. If you have development experience in other programming languages, you can learn Ruby more efficiently. In particular, the basic concepts of programming, such as variables and control statements, are not explained. Instead, it explains the characteristics of Ruby (differences from other programming languages), the basics of coding, refactoring, and test-driven development in Ruby. It is based on Ruby 2.4, and supplements 2.2 and 2.3 as appropriate.
