Full Description
This condensed code and syntax reference book presents the Raku (formerly known as Perl 6) scripting language in a well-organized format designed to be used time and again. It contains an easy-to-read and use guide to Raku for software application development.
Using this book will give you a feel for the language, as well as an introduction to the different features (such as object-oriented programming) that make Raku such a unique language. You won't find any technical jargon, bloated samples, drawn out history lessons, or witty stories in this book. Perl 6 Quick Syntax Reference is packed with useful information and is a must-have for any developer new to Raku.
