Synopses & Reviews
The open source Scala language is a Java-based dynamic scripting, functional programming language. Moreover, this highly scalable scripting language lends itself well to building cloud-based/deliverable Software as a Service (SaaS) online applications.
Written by Lift Scala web framework founder and lead Dave Pollak , Beginning Scala takes a down-to-earth approach to teaching Scala that leads you through simple examples that can be combined to build complex, scalable systems and applications.
This book introduces you to the Scala programming language and then guides you through Scala constructs and libraries that allow small and large teams to assemble small components into high-performance, scalable systems. You will learn why Scala is becoming the language of choice for Web 2.0 companies such as Twitter as well as enterprises such as Seimens and SAP. What you?ll learn Get running with the Scala programming language for functional Java, Java-based, and cloud-based/deliverable applications development, and more. Understand the basic syntax and mechanisms for writing Scala programs. Discover the techniques for and advantages of using immutable data structures. Create functional programming techniques for defining and managing concurrency. Use a complex type system and traits to define object-oriented programs. Work with Scala constructs and libraries that allow teams of any size to assemble small components into high-performance, scalable systems. Build complex systems based on the simple examples learned along the way through this book. Who this book is for
Java developers looking to reduce boilerplate, improve team performance, improve interteam dynamics, and build more scalable and robust systems. Also, this book will appeal to Java developers looking to do cloud-based development. Lastly, Ruby, Python, and Groovy programmers looking for a higher performance and a more robust language will benefit.

Synopsis
A curious attribute of the Scala programming language is that it expends a lot of expressive power in order to make the life of casual programmers simpler. For instance, Scala provides sophisticated type parametrization and traits so that more advanced programmers can design libraries which are at the same time general and easy to use. Casual users can profit from these libraries long before they discover the full power of Scala s abstraction constructs. The language design avoids the temptation of simply defining some handy primitives in the syntax, even if these primitives would be useful many times to many users. Instead of fixed primitives, the language design tries very hard to provide general construction principles, with which users can then define their own fundamental constructs, at no loss in syntactic convenience. This idea ranges from simple things, such as being able to define your own numeric data types, to full-blown domain-specific APIs such as Scala s support for concurrent actors. There is hardly a better example of this approach than David Pollak s Lift Web Framework for Scala. It leverages the full expressive power of Scala to provide a framework that s at the same time simple to use, powerful, and secure. David has been one of the earliest adopters of Scala. He has become a crystallization point for many important developments in the Scala community. He fostered the vibrant Lift community, organized the first Scala Lift Off conference in 2008, and promoted the adoption of Scala in many important industrial applications."
