Question

javascript BlackJack

i made a blackjack game, the code is below

//this method will return a shuffled deck

function shuffleDeck() {

//this will store array fo 52 objects

const decks = []

const suits = ['Hearts', 'Clubs', 'Diamonds', 'Spades']

const values = ['Ace', 'King', 'Queen', 'Jack', 'Ten', 'Nine', 'Eight', 'Seven', 'Six', 'Five', 'Four', 'Three', 'Two', 'One']

//run a loop till 52 times

for (let i = 0; i < 52; i++) {

//push a random item

decks.push({ suit: suits[Math.floor(Math.random() * suits.length)], value: values[Math.floor(Math.random() * values.length)] })

}

return decks

}

//function that will draw four cards form the deck

function draw(decks) {

return {

player: [decks[0], decks[1]],

computer: [decks[2], decks[3]]

}

}

//first shuffle the deck

const shuffled = shuffleDeck()

console.log((shuffled))

//now draw the card

const drawn = draw(shuffled)

console.log("\n\nDrawn Cards :" ,(drawn))

i want to make a node application that will listen for user input. this is what i have so far for it.

function startGame () {
let input;
input = prompt("Welcome to Blackjack. Do you want to play? (Y)es or (N)o").toUpperCase();
if (input == 'Y') {}
}

i am stuck on how to finish the startGame Function.

Answer 1

HI ,

You can follow a procedure where user gves an input ('Y' ) and then the game starts by shuffling the cards follwed by math.random function .

Your code will shiffle the card every time the game starts.

If the user inputs ('N'), the user exits .

#SAMPLECODESTRUCTURE

#userinput

function startGame () {
let input;
input = prompt("Welcome to Blackjack. Do you want to play? (Y)es or (N)o").toUpperCase();

if(input=='Y')

{

  

//this method will return a shuffled deck

function shuffleDeck() {

//this will store array fo 52 objects

const decks = []

const suits = ['Hearts', 'Clubs', 'Diamonds', 'Spades']

const values = ['Ace', 'King', 'Queen', 'Jack', 'Ten', 'Nine', 'Eight', 'Seven', 'Six', 'Five', 'Four', 'Three', 'Two', 'One']

//run a loop till 52 times

for (let i = 0; i < 52; i++) {

//push a random item

decks.push({ suit: suits[Math.floor(Math.random() * suits.length)], value: values[Math.floor(Math.random() * values.length)] })

}

return decks

}

//function that will draw four cards form the deck

function draw(decks) {

return {

player: [decks[0], decks[1]],

computer: [decks[2], decks[3]]

}

}

else

exit ;
