Getting Started with Scala,tion. The scalability of a program is defined in terms of its performance, while the scalability of a language has a broad ranging definition, in that the high scalability of Scala is a consequence of the fusion of object-oriented and functional programming. Scala’s functional programming constructs

Basics of Scala,apter is aimed at making you comfortable with the building blocks of the Scala language. Before embarking on an in-depth journey of Scala, this chapter introduces the basic concepts of Scala that should give you enough understanding to enable you to write useful programs. To that end, we had to leav

Object Orientation in Scala,tions, however, remains an arduous quest. An object in software is an abstraction of a real-world object, comprising essential properties and behaviors that set it apart from other objects. OOP is successful because object-oriented languages implement a number of principles such as encapsulation, in

Functional Programming in Scala,hen I was 21, I was astonished at how much the old man had learned in seven years". Functional programming is the old man that comes to the rescue when writing robust concurrent software. Functional programming treats computation as the evaluation of mathematical functions and avoids state and mutab

Pattern Matching,cornerstone of functional programming is pattern matching. Pattern matching provides a powerful tool for declaring business logic in a concise and maintainable way. Scala blends traditional functional programming pattern matching with object-oriented concepts to provide a very powerful mechanism for

Scala Collections,e distinct and independent mutable and immutable type hierarchies enable switching between mutable and immutable implementations much simpler. Scala’s object-oriented collections also support functional higher-order operations such as ., ., and . that let you use expression-oriented programming in c

Scala and Java Interoperability,s when you want to use existing Java libraries or framework. Scala code is often used in tandem with large Java programs and frameworks. Even though integration with Java is easy for the most part, we encourage you to use pure Scala as much as possible. When you are working with the Java library or

DSL and Parser Combinator,tations of this dichotomy. Domain-specific languages are just what they are called: domain specific. All programming languages are domain-specific languages when they come into existence, but that changes as they evolve. Domain-specific languages are created to solve problems in a certain area (or m
