Welcome to "Ruby Programming"! Ruby is a dynamic, object-oriented programming language that's been gaining popularity since its creation in 1995 by Yukihiro "Matz" Matsumoto. Known for its elegant syntax, readable code, and focus on developer happiness, Ruby has become a favorite among developers around the world.


        But why learn Ruby? First and foremost, Ruby is a joy to work with. Its syntax is designed to be easy to read and write, which makes programming in Ruby a delightful experience. Additionally, Ruby has a vibrant community that's constantly creating new tools, libraries, and frameworks to make development easier and more efficient. From web development with Ruby on Rails to game development with Gosu, there are many exciting areas of development to explore with Ruby.

        In this tutorial, we'll cover the fundamentals of Ruby programming, from basic concepts like variables and data types to more advanced topics like metaprogramming and concurrency. We'll also dive into web development with Ruby on Rails, one of the most popular web frameworks around. Whether you're new to programming or a seasoned developer, this book will provide a solid foundation in Ruby and the tools you need to start building your own projects.
