What Is Ruby?
Ruby is a free, open-source, dynamic programming language created by Yukihiro Matsumoto in Japan. It focuses on simplicity and developer happiness, with clean syntax that lets you write less code to get the same result. Ruby powers the popular Ruby on Rails web framework, along with command-line tools, scripts, and automation tasks.
On Windows, Ruby is installed through RubyInstaller, the official Windows distribution recommended on the Ruby website. It bundles the language with the MSYS2 development tools, so you can also install extra libraries called gems. Once installed, you can run Ruby scripts from the command prompt or from any code editor.

- Blocks and iterators: elegant tools for working with lists and collections in very few lines of code.
