Overview

One of 52 of cards that are used to play card games.

A card is comprised of one rank and one suit, with 13 ranks and 4 suits there are 52 unique playing cards. A card can be created in one of two ways:

The first method uses the Rank and Suit enumerators card = Card.new(Rank::KING, Suit::HEART)

The second method uses rank and suit values. card = Card.new(“KH”)

Rank and suit values are case insensitive, so these work as well card = Card.new(“Kh”) card = Card.new(“kH”)
