At this point, Ruby was 15 years old. These versions brought new changes to the language, such as:. Ruby was making the transition from a rebellious teenager to a strong adult as it turned 18 with Ruby 1.
Ruby 2. Among them are:. Unlike 1. The Ruby language was and is in its golden age. It brought several minor changes to the language. But the biggest news of 2. This version was mainly speed improvements and bugfixes.
Shortly after 2. Ruby is an interpreted, high-level, dynamic, general-purpose, open source programming language which focuses on simplicity and productivity. It was designed and developed in the mids by Yukihiro Matsumoto also known as Matz in the Ruby community in Japan. Here are some interesting facts about Ruby: Ruby came into existence as Yukihiro Matsumoto, wanted a scripting language more powerful than Perl, and more object oriented than Python.
The name Ruby for the language got originated in an online chat session between Matsumoto and Keiju Ishitsuka on February 24, before even any code was written in the language. Initially two names were suggested ie Coral or Ruby. The name Ruby was later chosen by Matsumoto in an email to Ishitsuka.
Ruby is often confused with Ruby on Rails, which is a server-side framework written in Ruby under the MIT License for implementing web applications. This is just a crazy idea.

We do not necessarily need to know how these DSL's are implemented, but we know they exist and know how to use them. As a beginner, you'll have to be aware of these abstractions particularly in programming and computer science and how they simplify programming and make computers easy to use. It's often confusing, for example, to read Rails or Rspec code without understanding Ruby because Rails and Rspec are DSLs operating at a higher level of abstraction.
The goal of this book is to show you Ruby, so that when you come across higher level abstractions and DSLs, you can recognize it as just Ruby code.
This book is written for the inexperienced or completely new programmer. If you apply the principles and techniques described in this book, you will build a strong basic knowledge of programming in Ruby. You may then use this knowledge to continue to learn more advanced concepts. This book will guide you through the common pitfalls and time-sinks that a beginner may experience. It will give you plenty of practice to commit basic Ruby syntax to long-term memory so you can focus on solving real-world problems and building real-world applications.
Being a programmer is often perceived as a difficult task. It is not. It does, however, require a certain temperament. When this temperament is understood and adopted, the work that a programmer does becomes less frustrating, more fun, and quite rewarding.
Perception of the difficulty of a given task is usually inversely proportional to the amount of patience the person attempting the task possesses. If you are patient with yourself and are willing to take the time to work through the exercises and apply the concepts, you will find yourself writing programs and solving problems with code very soon.
There is a shift in thinking that will take place and you will develop the ability to think deeply and clearly about a given problem. This process is often referred to as "flow" and can be very satisfying and engaging. It's one of the perks of programming! This is the first book of a two-book series on programming in Ruby.
