Description

Ruby can refer to a precious red gemstone, a computer programming language, or a type of text annotation used in East Asian documents. As a gemstone, it is a variety of the mineral corundum known for its red color, which is caused by chromium, and is used in jewelry and other applications like lasers. As a programming language, it is a dynamic, open-source language praised for its human-readable syntax and used extensively for web development, especially with the Ruby on Rails framework. As a text annotation, it provides small, phonetic or explanatory text next to a base text, primarily used to help with pronunciation in East Asian languages.
