The Ruby Way: Solutions and Techniques in Ruby Programming, 2/e (Paperback)

Description  

Ruby is an agile object-oriented language, borrowing some of the best features from LISP, Smalltalk, Perl, CLU, and other languages. Its popularity has grown tremendously in the five years since the first edition of this book.

 

The Ruby Way takes a “how-to” approach to Ruby programming with the bulk of the material consisting of more than 400 examples arranged by topic. Each example answers the question “How do I do this in Ruby?” Working along with the author, you are presented with the task description and a discussion of the technical constraints. This is followed by a step-by-step presentation of one good solution. Along the way, the author provides detailed commentary and explanations to aid your understanding.
