Learning Scala pdf

This book is meant for developers who have worked in object-oriented languages such as Java, Ruby, or Python and are interested in improving their craft by learning Scala. Java developers will recognize the core object-oriented, static typing and generic col‐ lections in Scala. However, they may be challenged to switch to Scala’s more expressive and flexible syntax, and the use of immutable data and function literals to solve prob‐ lems. Ruby and Python developers will be familiar with the use of function literals (aka closures or blocks) to work with collections, but may be challenged with its static, generic-supporting type system. For these and any other developers who want to learn how to develop in the Scala programming language, this book provides an organized and examples-based guide that follows a gradual learning curve.
