Understanding What is Ruby 

Ruby is a high-level, interpreted programming language celebrated for its simplicity, elegance, and powerful capabilities. Developed by Yukihiro "Matz" Matsumoto in 1995, Ruby blends elements of various programming paradigms, including functional and imperative styles. Its primary focus is on productivity and ease of use, with an intuitive and expressive syntax, making it particularly appealing to beginners.   

Ruby is object-oriented, meaning every value is an object, which allows for flexible and modular coding. It's widely used in web development, most notably with the Ruby on Rails framework, and is also employed in automation, data processing, and scripting tasks. Ruby's vibrant and welcoming community contributes to its ongoing growth and popularity in programming.
 

Evolution of Ruby 

Ruby was created by Yukihiro "Matz" Matsumoto, a Japanese computer programmer, in the mid-1990s. Matsumoto, an expert in multiple programming languages including Perl, Eiffel, Smalltalk, Lisp, and Ada, sought to combine the best features of these languages in Ruby.

Publicly released in 1995, Ruby didn't gain widespread acceptance until 2006. Since then, it has attracted a vast global user base, with programmers from various industries utilising it to develop some of the world’s leading applications. Ruby enthusiasts frequently gather in major cities for conferences. One of Ruby's greatest advantages is that it is entirely free and open source. Users can copy, modify, and distribute it without restrictions.

The Ruby on Rails web development framework, released in 2005, significantly boosted Ruby's popularity. Ruby on Rails transformed web development by enabling the creation of complex, user-friendly applications much faster than before.

Ruby on Rails quickly became popular among startup entrepreneurs, allowing small teams to build large applications efficiently. Major sites using Ruby Programming Language on Rails today include Shopify, Square, Instacart, Twitch, SoundCloud, GitHub, Kickstarter, Ask.fm, and Hulu.

Working of Ruby  

Ruby has evolved with numerous updates, enhancing performance, scalability, and security. Let us see how:
 

a) Interpreted Language: Ruby is an interpreted language, which means it executes instructions directly and freely without requiring prior compilation. This allows for rapid development and testing cycles. 

b) Object-Oriented Programming (OOP): Every element in Ruby, including primitive data types like integers and strings, is treated as an object. This OOP approach allows for encapsulation, inheritance, and polymorphism, providing flexibility and modularity in coding. 

c) Dynamic Typing: Ruby Language uses dynamic typing, checking variable types during runtime rather than compiling time. This feature adds to the language's flexibility and ease of use.  

d) Automatic Memory Management: Ruby employs a garbage collector that automatically allocates and frees up memory, reducing the risk of memory leaks and making memory management more accessible for developers. 

e) Convention Over Configuration: Especially evident in Ruby on Rails, this principle means the environment assumes reasonable defaults unless the developer specifies otherwise. This reduces the amount of configuration code needed for setup.  

f) Mixins and Modules: Ruby does not support multiple inheritances directly but offers mixins through modules. Modules are collections of methods and constants that can be included in classes, providing a way to share functionality.  

g) Blocks and Iterators: Ruby Language features blocks, which are huge chunks of code that can be passed to methods, and iterators, which are methods that return all collection elements one after another. This simplifies code for operations like loops. 

h) Metaprogramming: Ruby supports metaprogramming, the capability to write programs that write or modify other programs, including itself, during runtime. This is possible due to its dynamic nature.  

i) Extensive Standard Library and Gems: Ruby has a comprehensive standard library and supports gems – third-party libraries – allowing developers to extend functionality and reuse code easily. 

j) Interactive Ruby Shell (IRB): Ruby includes an interactive shell, IRB, which allows immediate execution and testing of Ruby commands, aiding in rapid development and debugging.

Advantages of Ruby 

Here are some advantages of Ruby: 

a) Ease of Learning and Reading: Ruby's simple and intuitive syntax makes it easy for beginners to learn and for developers to read and write code

b) Object-oriented Design: Everything in Ruby Programming Language is an object, promoting a modular and flexible approach to programming

c) Productivity and Efficiency: Ruby enables rapid development with less code due to its expressive syntax and powerful built-in methods

d) Dynamic Typing: Offers coding flexibility, with types checked at runtime

e) Robust Community and Ecosystem: A supportive community and a rich ecosystem of libraries (gems) enhance development capabilities

f) Metaprogramming: Ruby's metaprogramming abilities allow for more abstract and high-level programming

g) Open Source: Free to use, modify, and distribute, encouraging collaboration

h) Strong Framework Support: Ruby on Rails, a popular framework, streamlines web application development

i) Automatic Memory Management: The garbage collector handles memory allocation and deallocation, simplifying memory management

j) Interactive Shell (IRB): Facilitates testing and experimentation with immediate feedback, aiding quick learning and debugging.

What is Ruby Used for?  

Ruby is primarily used for web development, most notably with the Ruby on Rails framework, which simplifies and accelerates the creation of powerful web applications. Let us see more of its uses: 

a) Web Development: Ruby, primarily used with the Ruby on Rails framework, enables quick and efficient building of web applications.

b) Automation and Scripting: Ruby is ideal for writing scripts to automate tasks and processes due to its simplicity and readability.

c) Data Processing and Analysis: Ruby is useful for handling and manipulating data, particularly in smaller-scale data analysis projects.

d) Prototyping: Ruby is excellent for rapid prototyping of applications thanks to its fast development cycle and ease of use.

e) E-commerce and Online Marketplaces: Ruby powers many e-commerce platforms and marketplaces with its robust web development capabilities.

Ruby on Rails

Ruby is a high-level programming language, but its true acclaim is closely tied to Rails. Ruby on Rails is the application framework that catapulted Ruby into the spotlight, significantly boosting its popularity and establishing it as a preferred language for cloud development. Ruby on Rails is “an open-source web framework optimised for programmer happiness and sustainable productivity.”

The Ruby on Rails framework includes pre-written Ruby code for tasks such as communication, file handling, and database connections. By managing these tedious tasks, it allows developers to focus on problem-solving. A core principle of Rails is  Don’t Repeat Yourself DRY, which enhances the framework's efficiency.

There are over a million websites built with Ruby on Rails, spanning various industries. Notable examples include GitHub, Twitch, Bloomberg, SoundCloud, Hulu, Square, Basecamp, Airbnb, The Weather Channel, Instacart, and Twitter.
