The Ruby Workshop

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.

Summary

In this chapter, we learned about the fundamentals of Ruby and its key features. We started with the history of Ruby and the key programming paradigms the language supports that make it unique and powerful at the same time. We then learned about using Ruby code with the IRB and also learned how to write code in Ruby files and execute it. Next, we delved into the standard data types in Ruby, which are number, Boolean, and string. Here, we implemented various operations on variables along with commonly used string operations, such as string concatenation and interpolation.

In the next chapter, we will learn how to work with data structures such as arrays and hashes. We will explore the details of the various powerful methods associated with them, and we will also learn how to create our own Ruby methods and call them, which is the bedrock of day-to-day programming with Ruby.
