Describe the role of RubyGems in the Ruby ecosystem. How can you use RubyGems to manage dependencies?

RubyGems plays a crucial role in the Ruby ecosystem as a package manager. It provides a convenient way to distribute, share, and manage libraries, frameworks, and programs written in Ruby.

Managing these dependencies manually can be challenging, as it involves tracking versions, resolving conflicts, and ensuring all necessary components are installed. RubyGems automates this process, making it easier to include and manage external code. Using RubyGems, you can install gems from the official RubyGems repository or other custom repositories. T....
