In this post, I will introduce to you about the very reputable gems that are used the most by developers in 2021.
What is Gem?
Gem is a Ruby library. It is no different from the libraries of other common languages like PHP, Java or Python but the library in Ruby is called GEM. Only that simple. And of course when we install rails, we will use this command:
