RubyGem

A RubyGem is a packaged library or tool that extends the functionality of the Ruby programming language. Think of it as a ready-made module or set of code you can easily include in your projects to add features like authentication, data handling, or web development tools. Gems are managed through a system called RubyGems, which simplifies finding, installing, and updating these packages. This system helps developers save time by reusing well-tested code, fostering faster and more efficient software development.
