Gem

Gem is a package manager for the Ruby programming language, used to distribute and manage Ruby libraries and applications called 'gems'. It provides a standardized format for packaging Ruby code and a command-line interface to install, update, and manage dependencies. Gems are essential for Ruby development, enabling easy sharing and reuse of code across projects.

Also known as: RubyGems, gem command, Ruby Gem, gems, rubygems

Why learn Gem?

Developers should learn and use Gem when working with Ruby to efficiently handle dependencies, such as in web development with frameworks like Ruby on Rails or Sinatra. It simplifies project setup by automating the installation of required libraries, ensuring version compatibility, and is crucial for deploying Ruby applications in production environments.
