Create array of symbols

Question

Is there a cleaner way to do something like this?

%w[address city state postal country].map(&:to_sym) 
#=> [:address, :city, :state, :postal, :country]
         


        

Answer 1

%i[ ] Non-interpolated Array of symbols, separated by whitespace (after Ruby 2.0)

%I[ ] Interpolated Array of symbols, separated by whitespace (after Ruby 2.0)

%i[address city state postal country]

the cleanest way to do this is:

%w[address city state postal country].map(&:to_sym)
