Ruby is an object-oriented interpreted programming language that was developed by the Japanese programmer Yukihiro “Matz” Matsumoto.
The Ruby programming language combines a syntax inspired by Python and Perl with object-oriented programming functions similar to Smalltalk. The official implementation is distributed under a free software (open source) license.
What is ruby
Ruby is a high-level interpreted general-purpose programming language. The language is dynamically typed and uses garbage collection. It supports several programming paradigms, including procedural and functional programming.
Ruby is based on many other languages such as Perl, Lisp, Smalltalk, Eiffel, and Ada. This language has an elegant syntax that is naturally read and easy to write. The syntax is similar to that of C and Java, so Java and C programmers can easily learn it. Ruby supports all major platforms such as Windows, Mac, Linux.
As an interpreting script language, most instructions are executed directly without a compiler having to translate the code into machine-language instructions. Ruby programmers also have access to the powerful features of RubyGems.
RubyGems is a powerful package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries, in a stand-alone format called “gem”, as well as tools to easily manage the installation of gems on a server.
What are the benefits of Ruby?
One of the great things about Ruby is that it makes it easy and quick to build web applications. The language fulfills this goal very well. Because of this, this language is much less of a pain to work with than many other programming languages.
Ruby is also open source and free to use. The language may be copied, changed, and redistributed. Because Ruby can be modified, programmers can make the changes they need and code without limitation.
Another advantage of Ruby is garbage collection, which is automatic memory management and cleaning. If the operating system allows, Ruby can load extension libraries dynamically.
One of the most noticeable advantages of Ruby is its ability to call methods and functions. Brackets, which are normally found in methods and functions in other programming languages, are not required here, especially if no arguments are required.
To speed up application development, Ruby can be used in conjunction with an IDE (Integrated Development Environment). This way, a programmer can write, run, and debug programs with relative ease.
Other advantages of the language are:
- Ruby allows you to embed code. For example, Ruby can be embedded in Hypertext Markup Language (HTML).
- The language supports several programming paradigms such as procedural programming, object-oriented programming, as well as functional programming, which makes it unique in the programming world.
- Libraries and packages are managed via the Rubygems central library management system.
- Easy to learn, especially for beginners.
- Great support from an active online community.
How common is Ruby?
Ruby is very flexible and is therefore used in many areas. The language is very often used for scripting on web servers, where the “Ruby on Rails” framework is also strongly represented. Ruby is also used as a scripting language for complex bash scripts due to its flexible syntax.
Ruby can be used as a scripting language, but it can also be compiled into bytecode used by the Java Virtual Machine. Ruby is currently ranked 11th among the world’s most popular programming languages.
Ruby is often confused with Ruby on Rails, a server-side framework written in Ruby under the MIT license to implement web applications.
The story of Ruby
The programming language Ruby was developed by the Japanese programmer Yukihiro Matsumoto (Matz) from 1993 and published in 1995.
To create a powerful language, Matsumoto took from the best of his favorite programming languages, Perl. The object-oriented language was also influenced by Smalltalk, Ada, Eiffel, and Lisp.
At that time, many of the features known in later versions of Ruby were already in place, including object-oriented design, classes with inheritance, iterators, exception handling, and garbage collection. Initially, the names Ruby and Coral were suggested for the language, then Matsumoto chose Ruby.
The advent of the “Ruby on Rails” framework in the 2000s had a major impact on web app development through innovative features such as seamless database table creation, migrations, and rapid application development. The influence of Ruby on Rails on other web frameworks is evident to this day.
Ruby was developed primarily as a universal scripting language that fully supports being used on a web server. The language is primarily used for web applications, standard libraries, servers, and other system utilities.
Metaprogramming is one of the languages’ great strengths.
Ruby is becoming increasingly popular with developers these days as new frameworks are provided for developing applications. This also helps with maintaining the code.
