Scala 3--A Clear, Concise Guide
Scala 3 is concise, consistent, flexible, robust, and efficient, but
there's a lot to learn and navigating features and improvements can be
challenging. Scala for the Impatient, Third Edition, is a complete
yet concise guide that reflects the major enhancements of Scala 3, from
improved syntax and revamped type system to powerful contextual
abstractions.
This indispensable tutorial offers a faster, easier pathway for learning
today's Scala. Horstmann--author of the programming classic, Core
Java--covers everything working developers need to know, focusing on
hands-on solutions, not academic theory. Given the size and scope of
Scala 3, there's plenty to cover but it's presented in small chunks
organized for quick access and easy understanding, with plenty of
practical insights and focused sample code.
- Get started quickly with Scala 3 interpreter, syntax, tools, and
current usage
- Master core language features: functions, arrays, maps, tuples,
packages, imports, exception handling, and more
- Design and build better object-oriented code with Scala 3
- Use Scala for real-world programming tasks: working with files,
regular expressions, and processes
- Work with higher-order functions and the powerful Scala collections
library
- Create concurrent programs with Scala futures
- Understand the Scala type system, including revamped enums,
intersection and union types, and enhanced type inference
- Use contextual abstractions to easily extend class hierarchies, enrich
existing classes, perform automatic conversions, and elegantly hide
tedious details
- Apply advanced "power tools" such as annotations and given values
- Discover how to "program with types," analyzing and generating types
at compile time
- Get a taste of what's now possible with Scala macros
If you're a Java, Python, C++, or C# programmer who's new to Scala or
functional programming--or even if you've already used earlier versions
of Scala--this guide will help you write code that's more robust, more
efficient, and more secure.
