Eloquent Ruby (Addison-Wesley Professional Ruby Series)

It’s easy to write “correct” Ruby code. But it’s far harder to gain the fluency needed to write __great__ Ruby code. To do that, you need to go beyond syntax and absorb the “Ruby way” of thinking and problem solving. In **__Eloquent Ruby,__** Russ Olsen helps you understand Ruby like true Rubyists do—so you can leverage its immense, surprising power. Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the “Ah Ha!” moments when it suddenly becomes clear __why__ Ruby works the way it does and __how__ you can take advantage of its unique approach. **__Eloquent Ruby__** starts small, answering tactical questions focused on a single statement, method, test, or bug. You’ll learn how to write code that actually looks like Ruby (not Java); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for. Next, Olsen turns to bigger questions related to building methods and classes. You’ll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code—and why you’ll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages. The newest book in the renowned Addison-Wesley Professional Ruby Series, **__Eloquent Ruby__** will help you “put on your Ruby-colored glasses” and get results that make you a true believer.
