Part 1: Getting Started

As with any programming book, we need to start by introducing the language, including how to use it, its basic features and semantics, as well as touching on some commonly used patterns it makes use of. This part focuses on just that, getting started with Crystal, but with a bias toward readers with knowledge of some other programming language, but no previous contact with Crystal itself.

This part contains the following chapters:

• Chapter 1, An Introduction to Crystal
• Chapter 2, Basics Semantics and Features of Crystal
• Chapter 3, Object-Oriented Programming
