Ruby is an interpreted, high-level, general-purpose programming language which supports multiple programming paradigms. It was designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an object, including primitive data types.

Unlike languages such as C and C++, a scripting language doesn’t talk directly to hardware. It’s written to a text file and then parsed by an interpreter and turned into code. These programs are generally procedural in nature, meaning they are read from top to bottom.

Object-oriented languages, on the other hand, break out pieces of code into objects that can be created and used as needed. You can reuse these objects in other parts of the program, or even other applications.

Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.

Ruby is seen as a flexible language, since it allows its users to freely alter its parts. Essential parts of Ruby can be removed or redefined, at will. Existing parts can be added upon.
