Overview of this book

The beauty of Ruby is its readability and expressiveness. Ruby hides away a lot of the complexity of programming, allowing you to work quickly and 'do more' with fewer lines of code. This makes it a great programming language for beginners, but learning any new skill can still be a daunting task. If you want to learn to code using Ruby, but don't know where to start, The Ruby Workshop will help you cut through the noise and make sense of this fun, flexible language. You'll start by writing and running simple code snippets and Ruby source code files. After learning about strings, numbers, and booleans, you'll see how to store collections of objects with arrays and hashes. You'll then learn how to control the flow of a Ruby program using boolean logic. The book then delves into OOP and explains inheritance, encapsulation, and polymorphism. Gradually, you'll build your knowledge of advanced concepts by learning how to interact with external APIs, before finally exploring the most popular Ruby framework ? Ruby on Rails ? and using it for web development. Throughout this book, you'll work on a series of realistic projects, including simple games, a voting application, and an online blog. By the end of this Ruby book, you'll have the knowledge, skills and confidence to creatively tackle your own ambitious projects with Ruby.

Introduction

In the previous chapter, we learned about code reusability and how to clean up our code base by extracting common functionality and logic from modules that can be included as needed throughout our project, preventing unnecessary code duplication.

This is an important concept to grasp as it forms the base for Ruby's excellent package management system known as RubyGems, which we will dive into further in this chapter.

Most applications consist of inputs and outputs. Facebook will have data in the form of photos and status updates (as input), and users, in turn, will see other users' photos and status updates (as output). Additionally, a banking application will load data from a database (as input) and present it to the user in the form of charts and tables (as output). The input data sources will vary per application, but the concept of inputs and outputs is essentially the same.

Data is fed into the application, some sort of processing is performed,...
