Experimenting with Poker game functions

API
4

I tried the following commands using create function keywords to split up the logic and got a simple way to handle 3 events at once.

/* create a function to create a deck of poker cards. create a function to deal 5 cards from the deck. create a function to get the value of hands dealt. */

var deck = [];
var suits = ['spades', 'hearts', 'diamonds', 'clubs'];
var values = ['ace', '2', '3', '4', '5', '6', '7', '8', '9', '10', 'jack', 'queen', 'king'];

function createDeck() {
  for (var suit of suits) {
    for (var value of values) {
      deck.push(value + ' of ' + suit);
    }
  }
}

function dealCards() {
  var hand = [];
  for (var i = 0; i < 5; i++) {
    hand.push(deck.pop());
  }
  return hand;
}

function getHandValue(hand) {
  var value = 0;
  for (var card of hand) {
    var cardValue = card.split(' ')[0];
    if (cardValue === 'ace') {
      value += 11;
    } else if (cardValue === 'jack' || cardValue === 'queen' || cardValue === 'king') {
      value += 10;
    } else {
      value += parseInt(cardValue);
    }
  }
  return value;
}

The value of a hand in poker is not determined solely by individual card values, but even so it’s a step in the right direction. After that It was a simple matter to call those functions and log the results…

/* call createDeck */
createDeck();

/* console.log(getHandValue(dealCards)); */
console.log(getHandValue(dealCards()));
