"Every self respecting Senior Software Engineer out there should build
their own code editor, even if just as a toy app to later be discarded in
favor of another code editor (though they might grow to prefer their own).
And, if they are Rubyists, they should build their code editor in Ruby
(whether using MRI Ruby, JRuby or Opal Ruby). If you think of yourself as a
Ruby Senior Software Engineer, but cannot build your own code editor in
Ruby, there are serious holes in your skillset!! Explore Glimmer libraries
for many Ruby options to help you start the code editor building challenge
and journey."
