| 520 | |a How Ruby Works Under the HoodRuby is a powerful programming language with a focus on simplicity, but beneath its elegant syntax it performs countless unseen tasks. Ruby Under a Microscope gives you a hands-on look at Ruby's core, using extensive diagrams and thorough explanations to show you how Ruby is implemented (no C skills required). Author Pat Shaughnessy takes a scientific approach, laying out a series of experiments with Ruby code to take you behind the scenes of how programming languages work. You'll even find information on JRuby and Rubinius (two alternative implementations of Ruby). | ||
