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:

The book is great, and Crystal is an awesome programming language. Main complaint is that the e-book doesn't have color images, which needs to be acquired from an external link, however said link returns "access denied" and doesn't let me access it. Not a huge issue as the code examples are available externally, but it's a shame the digital experience can't be a bit nicer. Still highly recommended to anyone interested in Crystal. UPDATE: The support team has resolved the issue and provided me with a working link to the color images, the rating has been updated to reflect this.
