In Detail
Crystal is a general-purpose, object-oriented programming language developed as an open source software. It is a combination of two strong programming languages – Ruby and C. It is inspired by the syntax of Ruby and is a compiled language, allowing it to run blazingly fast with a very low memory footprint.This book will be your guide to get started with Crystal Programming language.
You will begin by understanding the language fundamentals and Crystal Programming enviornment before moving into the syntactical structure of Crystal. From here, you will delve into the data types and objects with Crystal. You will look into Data Structures and operators and will learn to work with Classes and Modules Going forward, you will be introduced to Object Oriented Programming and Functional programming with Crystal. You will also learn to build a simple web application with Kemal– web framework for Crystal. Finally, you will also be introduced to concurrent programming with Crystal with its in-build concurrency models.
