Gem packages

Gem packages are pre-made code collections used in Ruby programming to add specific features or functionalities to applications. Think of them like apps or plugins that can be easily integrated into a project, saving time and effort by providing ready-to-use tools for tasks like handling data, connecting to web services, or managing user interfaces. They are managed through RubyGems, a package manager that streamlines installing, updating, and sharing these code packages to ensure projects are efficient and maintainable.
