Scala Features
Scala, short for Scalable Language, is a hybrid functional programming language. It was created by Martin Odersky and was first released in 2003 (for more information, see “A Brief History of Scala” in Appendix 2, Web Resources). Here are some of the key features of Scala:
-
It supports both an imperative style and a functional style.
-
It is purely object-oriented.
-
It enforces sensible static typing and type inference.
-
It is concise and expressive.
-
It intermixes well with Java.
-
It is built on a small kernel.
-
It is highly scalable, and it takes less code to create high-performing applications.
-
It has a powerful, easy-to-use concurrency model.
You’ll learn more about each of these features throughout this book.
