Not only for strings, but arrays and hashes too
exclude? is defined as !include?, meaning it is the exact opposite of include? . See the source.
This means that it works for Arrays and Hashes too, as well as for Strings.
It works for Arrays:
>> [nil].exclude?(nil) => false >> [nil].include?(nil) => true >> ["lala"].include?(nil) => false >> ["lala"].exclude?(nil) => true
And for Hashes:
>> params = {} => {} >> params[:db] = "lol" => "lol" >> params.exclude?(:db) => false >> params.include?(:db) => true >>
