EmptyFrozen

Need to return something other than nil? We've all needed to from time to time 😅 . Sometimes no mutation will be done to this returning value and sometimes there will; empty_frozen's got you covered either way.

Add this line to your application's Gemfile:

gem 'empty_frozen'

And then execute:

$ bundle

Or install it yourself as:

$ gem install empty_frozen

require 'empty_frozen'

...

def space_instagram
  return Hash.empty if cadet?

  visited.celestial.each_with_object({}) do |celestial, hsh|
    hsh[celestial] = selfies_taken_at celestial
  end
end

def potential_pet_recommendations
  return Array.empty_frozen if has_no_heart?

  liked.animals.map(&:species).uniq
end

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
