📘 What is Ruby?
Ruby is a dynamic, object-oriented programming language created in 1995 by Yukihiro Matsumoto. It emphasizes simplicity and productivity, with a syntax that is natural to read and easy to write. Ruby is best known for powering the Rails framework, which revolutionized web development with its “convention over configuration” philosophy.
💻 Coding Example
