Question

Im doing a little project which involves

• country list
• country abbreviation list e.g UK, US.
• dial code.

if a user enters +44, it should pull the country and country abbreviation

I was wondering what the best way to implement this is? shall i create 3 different hashes? or use nested hashes?

Answer 1

Before reinventing the wheel, you should check existing solutions like the countries gem:

c.number #=> "840"
c.alpha2 #=> "US"
c.alpha3 #=> "USA"
c.country_code #=> "1"
c.national_destination_code_lengths #=> 3
c.national_number_lengths #=> 10
c.international_prefix #=> "011"
c.national_prefix #=> "1"
