This book will teach you to write simple console applications in Ruby. When you come to the end of this book, you will be able to write Ruby scripts that
interacts with the user, interacts with the file system, etc. Although Ruby is very useful on the web, this book does not contain any lessons on web
specific development because the prerequisite of that is knowing basic web development using languages such as HTML, CSS, Javascript, etc. Having
said that, if you are a web developer or know even the basics of web development using HTML, CSS, Javascript, etc., the basic knowledge ofRuby that you gain from this book should be enough for you to self-learn web development using Ruby.
