The Well-Grounded Rubyist, Fourth Edition highlights the most useful parts of the language with examples designed to spark "aha!" moments. This is not a dry syntax reference or overly technical deep dive. You'll go from your first Ruby program all the way to sophisticated topics like reflection, threading, and recursion.
