Deal 13 cards

Try it

Then sort the hand.

Try it

First we define an Array prototype function that allows us to retrieve the Array index of a value if it exists. We will use this Array method to rank the cards according to their index values in the Array "N":

N=[2,3,4,5,6,7,8,9,10,"J","Q","K","A"]
Array.prototype.getIndex=function(val){
for(i=0;i<this.length;i++){
if(this[i]==val) return i;
}
return -1;
}

Example, remember that "A" is an Array containing a deck of cards:

var newHand=A.shuffle(200).slice(0,13);
var firstCard=newHand[0];

firstCard value is the card's suit followed by a space, followed by the face value. The value of the Ace of Hearts, for instance, would be "♥ A". We simply parse out the face value, it's everything following the space.

var firstCardFaceValue = firstCard.substring(firstCard.indexOf(" ")+1);

Then we look for this value in the Array "N"

var firstCardRank=N.getIndex(firstCardFaceValue);

Try it:

Hand
First Card
Rank
