About Ruby

Ruby was developed by Yukihiro "Matz" Matsumoto (Japan) in the mid-1990s. It was made popular by the Ruby on Rails framework, a full-stack web framework.

Ruby is an interpreted programming language with a focus on simplicity and productivity (Syntax easy to read and write, Garbage collection, dynamically typed language, ...).

Ruby is mainly getting used for a web application, libraries and other system utilities.

Why uses a code checker online? The interest is quite limited, but it can help in certain situations, for example when you don't have access to a development environment, and you want to test the validity of a small script.

As soon as I have some time, I will add Ruby version 3 support.
