What is Ruby?
Ruby is a computer-programming language. To be more specific, it is an object-oriented, dynamically typed, scripting, programming language. You will find Ruby to be very legible, and readable compared to most programming languages. It was publicly released in 1995 and is open-source and freely available for download — read here for Installation instruction for Ruby.
There is an active community which works with Matz and the now well-establish “Ruby core” team of developers around the world to provide frequent updates to improve the language.
