What is Ruby

The objective of Ruby’s development was to make it act as a sensible buffer between human programmers and the underlying computing machinery. This book is written for the inexperienced or completely new programmer.

But unlike Python, which focuses on a single, unambiguous solution for every problem, Ruby projects try to take multiple different approaches to problem-solving. As you might have guessed, there are benefits and disadvantages to both methods, depending on your project. Perhaps most importantly, Ruby is a highly versatile and portable language. It can be used just as easily on Windows, macOS, Linux, and even UNIX and DOS. No matter what programming job you want to get done, there’s a gold chance you can do it in Ruby. Perhaps best of all, Ruby programming skills are highly in-demand in the marketplace, and being able to code using Ruby can make you a very versatile and useful programmer.

The reference implementation, JRuby, and Rubinius are all able to run Rails unmodified in a production environment. The original Ruby interpreter is often referred to as Matz’s Ruby Interpreter or MRI. This implementation is written in C and uses its own Ruby-specific virtual machine. According to the Ruby FAQ, the syntax is similar to Perl’s and the semantics are similar to Smalltalk’s, but the design philosophy differs greatly from Python’s.

Yukihiro “Matz” Matsumoto, creator, designer and lead developer of Ruby and author of Ruby in a Nutshell, which has been expanded and revised to become this book. Learn how to define your own methods, as well as how to use blocks to develop powerful sorting algorithms. Concise and readable, it is easy to pick up but also plenty powerful.

Learning Ruby[edit | edit source]

Matsumoto was an expert on multiple programming languages at the time, including Perl, Eiffel, Smalltalk, Lisp, and Ada. When creating Ruby, he tried to combine what he thought were the best elements of each of these languages.

One of the key concepts of Rails is DRY — Don’t Repeat Yourself — which is key to the framework’s efficiency. The Ruby Application Archive, which hosted applications, documentation, and libraries for Ruby programming, was maintained until 2013, when its function was transferred to RubyGems.

Features of Ruby

In the world of computer programming, there is an infinite amount of information to learn. It intentionally avoids certain topics that are not beneficial to the beginner.

• The reference implementation, JRuby, and Rubinius are all able to run Rails unmodified in a production environment.
• Ruby was invented by Yukihiro “Matz” Matsumoto, a Japanese computer programmer, in the mid-1990s.
• It was designed with an emphasis on programming productivity and simplicity.
• Get Mark Richards’s Software Architecture Patterns ebook to better understand how to design components—and how they should interact.
• The bytecode compiler and most core classes are written in pure Ruby.

Reading about programming and the act of programming are very different things. Learn about arrays and hashes, including how to iterate over these data structures. In this course, you will gain familiarity with Ruby and basic programming concepts—including variables, loops, control flow, and most importantly, object-oriented programming. Ruby is a server-side scripting language similar to Python and PERL. Ruby is a general-purpose, interpreted programming language. You can find the name Yukihiro Matsumoto on the Ruby mailing list at -lang.org.

Yukihiro wanted to create a scripting language that leveraged object-oriented programming and increase code reuse to help speed up development. And so the Ruby programming language was born, using simple language and syntax to handle data and logic to solve problems. Python’s property descriptors are similar, but come with a trade-off in the development process. Ruby’s design forces all instance variables to be private, but also provides a simple way to declare set and get methods. Unlike languages such as C and C++, a scripting language doesn’t talk directly to hardware. It’s written to a text file and then parsed by an interpreter and turned into code. These programs are generally procedural in nature, meaning they are read from top to bottom.

Ruby Hooks add the ability to know when new methods are defined et al.

Learn to program in Ruby, a flexible and beginner-friendly language used to create sites like Codecademy.

The Ruby programming language is a highly portable general-purpose language that serves many purposes. Rubinius, a C++ bytecode virtual machine that uses LLVM to compile to machine code at runtime. The bytecode compiler and most core classes are written in pure Ruby.

Some of these include automation, command-line tools, static site generation, DevOps, web scraping, and data processing. It was created in 1993 by Yukihiro Matsumoto of Japan. The 2020 Stack Overflow Developer Survey names Ruby the 14th most popular programming language in the world with 7.1% of respondents being Ruby on Rails developers. Ruby stands alone as a high-level programming language.

Its creator, Yukihiro Matsumoto, aka “Matz”, released it to the public in 1995. When it comes to web development, the framework Ruby on Rails is used. Rails uses ready-made conventions that save developers time on configuring projects. It also has code generators to create parts of an application automatically, letting programmers write less code.
