Ruby is a high-level, interpreted programming language that was developed in the mid-1990s by Yukihiro Matsumoto in Japan. It’s designed for simplicity and productivity, with an elegant syntax that is natural to read and easy to write. Ruby is utilized in many areas, but it is notably used in web development and is the basis for the popular Ruby on Rails web application framework.


The phonetic spelling of the keyword “Ruby” is: Roo-bee. In the International Phonetic Alphabet (IPA), it is: /ˈruːbi/

Key Takeaways

  1. Ruby is a high-level, interpreted programming language known for its flexibility and readability. It supports multiple programming paradigms including procedural, object-oriented, and functional programming.
  2. Ruby on Rails, a popular web application framework, is written in Ruby, which indicates its wide usage and importance in creating web-based applications.
  3. Ruby uses dynamic typing and has a garbage collector which makes it a versatile language for prototyping and data analysis as well as web development.


Ruby is an important term in technology because it is a dynamic, reflective, object-oriented, general-purpose programming language. Ruby was intentionally designed with an emphasis on simplicity and productivity, and it has an elegant syntax that is considered natural to read and easy to write. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. Ruby has also gained significant popularity due to its use in Ruby on Rails, a server-side web application framework. This has made Ruby crucial in the field of web development and web applications, as the Rails framework significantly simplifies the task of creating complex websites.


Ruby is a high-level, interpreted programming language that prioritizes simplicity and productivity. Created in the mid-1990s by Yukihiro “Matz” Matsumoto in Japan, the core philosophy of its design is to make programming enjoyable for programmers. It features a syntax that is easy to read and write, making it user-friendly especially for beginners who want to learn about programming. The language supports multiple programming paradigms, including procedural, object-oriented, and functional programming.The main purpose of Ruby is to create fully functional web applications. Ruby on Rails, a popular web application framework that is implemented in Ruby, has often been associated with this programming language, capitalizing on Ruby’s user-friendly attributes to simplify tasks such as building complex websites or managing databases. Furthermore, the language also focuses on testing, making it quicker and easier for programmers to find and fix errors in their code. Notably, many large tech companies, including Airbnb, Twitch, GitHub, and Twitter were initially built with Ruby on Rails.


1. Twitter: In the early days, Twitter leveraged Ruby on Rails as their primary technology for building the platform. Although they have now diversified their technology stack to scale for the large user base, Ruby played a significant role in Twitter’s initial development.2. Airbnb: The online marketplace for hospitality service for people to lease or rent short-term lodging including holiday cottages, apartments, home-stays, hostel beds, or hotel rooms, uses Ruby on Rails for their web application. This tech-stack is chosen for its simplicity and easiness to rapid development.3. Github: The popular platform among developers to host and review code, manage projects, and build software also uses Ruby on Rails. Its Rails application is a monolithic application, which means there is a single, comprehensive program with many dependencies. This certainly is a testament to Ruby’s resilience for handling complex and large-scale tasks.
