Notation
H - Hearts
C - Clubs
D - Diamonds
S - Spade
1 - Ace
2 - 10 2 - 10
J - Jack
Q - Queen
K - King
I accept there are other ways to do this, lol. (Array for example)

I dont like the 10. change them to T?
I don't like the 1. Change them to A?
We can shuffle a deck
Looks good, 😀
My verbose and overly engineered version below 😆, I've have added card value and a couple of functions for shuffling / picking n number of cards...
