DESCRIPTION:Most successful Ruby applications become more difficult to maintain as the codebase grows in size.
Polished Ruby Programming, 2nd Edition provides you with the skills and advice you need to design Ruby programs
and libraries that are robust, performant, scalable, and maintainable.
The book takes you through possible implementation approaches for many common programming situations,
discusses the trade-offs inherent in each approach, and explains why you may sometimes choose to use different approaches.
You'll start by learning fundamental Ruby programming principles, such as correctly using core classes,
class and method design, variable usage, error handling, and code formatting.
Then you’ll move on to higher-level topics such as library design, metaprogramming, domain-specific languages, and refactoring.
Finally, you'll learn about the pros and cons of different approaches to concurrency,
what you should consider when deciding whether to use static types in your Ruby code, and how best to optimize your Ruby code.
