Get to grips with the fundamentals of the Ruby programming language and learn how to build your own applications with the help of real-world examples and hands-on activities Key Features Learn the fundamentals of Ruby object-oriented programming (OOP) Use the Ruby on Rails framework to build interactive web applications Discover how to quickly build complex programs with fewer lines of code Book DescriptionThe 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. What you will learn Master the syntax and features of Ruby to build useful applications Use common design patterns to simplify code and improve efficiency Understand how to implement object-oriented programming with Ruby Explore ways to fetch, process, and output data Work with public APIs and create reusable RubyGems Debug code to troubleshoot application behavior Create interactive web applications with Ruby on Rails Who this book is forThe Ruby Workshop is designed for anyone who is new to Ruby and wants a practical introduction to the language. Whether you're completely new to programming, or have experience in another language and want to broaden your skillset, this book will quickly get you up and running.

This is a step-by-step book that builds on your knowledge by adding to an example app over the course of each chapter. Each topic uses example code that can be compiled and tested to show how things work practically instead of just telling you the theory. Complicated tasks are broken down into easy to follow steps with clear explanations of what each line of code is doing.Whether you are a novice to iOS development or looking for a simpler alternative to Objective-C; with RubyMotion iOS Development Essentials, you will become a pro at writing great iOS apps
