Ruby is a programming language that Yukihiro "Matz" Matsumoto invented during the mid-1990s. Matz was an expert on several computer languages such as Ada, Smalltalk, Eiffel, Lisp and Per. Ruby is his attempt to create a language that combines the best elements of several existing languages.
What separates Ruby from the rest is the simplicity of the language and yet still remains effective. It's a careful balance between imperative and functional programming, allowing it to be intuitive and natural. For the fans, Ruby is often considered artful and beautiful.
Ruby is versatile enough that it can be used for a myriad of purposes such as data scraping, web scrapping, DevOps, static site generation, common-line tools, and automation. Having said that, Ruby is most popularly used for web development.
Another notable characteristic of Ruby is that it's very versatile. It can be used on multiple operating systems such as DOS, UNIX, Linux, macOS, and Windows.
