Chapter 2. Building Blocks of Scala

"You can't build a great building on a weak foundation. You must have a solid foundation if you're going to have a strong superstructure."

- Gordon B. Hinckley

Our aim as programmers is to provide a solution to a problem through some logical implementation. Programming languages work as a tool for just that. When we implement a solution to a problem, we must be able to describe the problem (specification) so that a programming language can verify (verification) whether the solution indeed solves the problem.

Problem Solution

For implementation, we use various programming constructs, which are basic entities with some syntactic rules. These entities work as building blocks for any programming language. In Scala, we have similar syntax to almost any other programming language. We use keyword/name/classifier/bound-entity. In this chapter, our aim is to get familiar with some of the building blocks. We'll go through:

The val and var keywords
Literals
Data types
Type...

This book teaches you how to build and contribute to Scala programs, recognizing common patterns and techniques used with the language. You’ll learn how to write concise, functional code with Scala. After an introduction to core concepts, syntax, and writing example applications with scalac, you’ll learn about the Scala Collections API and how the language handles type safety via static types out-of-the-box. You’ll then learn about advanced functional programming patterns, and how you can write your own Domain Specific Languages (DSLs). By the end of the book, you’ll be equipped with the skills you need to successfully build smart, efficient applications in Scala that can be compiled to the JVM.

Mastering Functional Programming

Mastering Functional Programming

In large projects, programmers tend to get overwhelmed by their complexity. It can be hard to keep track of all the interdependencies in the code-base and how its state changes on runtime. The solution to these problems is Functional Programming, a paradigm specifically designed to deal with the complexity of software development. Mastering Functional Programming will show you how right abstractions can reduce complexity and make code easy to read and understand. It will guide you through this programming style, from the very first steps to the most advanced patterns and libraries to date.

Introduction to JVM Languages

Introduction to JVM Languages

Anyone who knows software development knows about the Java Virtual Machine. The Java Virtual Machine is responsible for interpreting Java byte code and translating it into actions. In the beginning, Java was the only programming language used for the JVM. But increasing complexity of the language and the remarkable performance of the JVM created an opening for a new generation of programming languages. If you want to build a strong foundation with the Java Virtual Machine and get started with popular modern programming languages, then this book is for you.
