About Ruby

Ruby is like a poet in the programming world - it’s not just about getting things done, but about doing them with style. Created by Yukihiro "Matz" Matsumoto in the mid-1990s, Ruby is a dynamic, object-oriented language where everything is an object - even numbers and nil. It is designed to be intuitive and readable, making it popular among both beginners and experienced developers.

Ruby is perhaps best known for its powerful web framework, Ruby on Rails. Rails made it possible to build complex web applications quickly and efficiently and has powered sites like GitHub, Airbnb, and Shopify. With Rails you get a full toolbox for creating modern web services - from the database to the user interface.

Although Ruby no longer tops popularity charts, it still enjoys a passionate community and a rich ecosystem of libraries and tools. If you value code that is both powerful and beautiful, Ruby might be the language to make your developer heart beat a little faster.
