STEPS IN SCALA
An Introduction to Object-Functional Programming
Object-functional programming is already here. Scala is the most prominent rep-
resentative of this exciting approach to programming, both in the small and in the
large. In this book we show how Scala proves to be a highly expressive, concise,
and scalable language, which grows with the needs of the programmer, whether
professional or hobbyist.
Read the book to see how to:
• leverage the full power of the industry-proven JVM technology with a language that could
e from the future;
• learn Scala step-by-step, following plete introduction and then dive into spe-
cially chosen design challenges and implementation problems, inspired by the real-world,
software engineering battlefield;
• embrace the power of static typing and automatic type inference;
• use the dual object and functional oriented bined at Scala’s core, to see how
to write code that is less “boilerplate” and to witness a real increase in productivity.
Use Scala for fun, for professional projects, for research ideas. We guarantee the
experience will be rewarding.
