Summary:

Although Ruby is an easy language to learn, in the heat of action you may find that you can't remember the correct syntax for a conditional or the name of a method. This handy pocket reference offers brief yet clear explanations of Ruby's core components, from operators to reserved words to data structures to method syntax, highlighting those key features that you'll likely use every day when coding Ruby. Whether you've come to Ruby because of the Rails web development framework --Ruby's killer app -- or simply because it's a relatively clean, powerful and expressive language
