How to build Blackjack

Did use js,html and some css to build a blackljack game.

// object
let player = {
  name: "ben",
  chips: 200,
  sayHello: function () {
    console.log("Heisann!");
  },
};

player.sayHello();

let cards = []; // array -ordered list of item
let sum = 0;
let hasBlackJack = false;
let isAlive = false;
let message = "";

let messageEl = document.getElementById("message-el");
let sumEl = document.querySelector("#sum-el");
let cardsEl = document.querySelector("#cards-el");

let playerEl = document.getElementById("player-el");
playerEl.textContent = player.name + ": $" + player.chips;

// Create a function, getRandomCard(), that always returns the number 5

// FLOR REMOVE DECIMALS

function getRandomCard() {
  // if 1     -> return 11
  // if 11-13 -> return 10
  let randomNumer = Math.floor(Math.random() * 13) + 1;
  if (randomNumer > 10) {
    return 10;
  } else if (randomNumer === 1) {
    return 11;
  } else {
    return randomNumer;
  }
}

function startGame() {
  isAlive = true;
  let firstCard = getRandomCard();
  let secondCard = getRandomCard();
  cards = [firstCard, secondCard];
  sum = firstCard + secondCard;

  renderGame();
}

function renderGame() {
  cardsEl.textContent = "Cards: ";

  for (let i = 0; i < cards.length; i++) {
    cardsEl.textContent += cards[i] + " ";
  }

  sumEl.textContent = "sum: " + sum;
  if (sum <= 20) {
    message = "Do you want to draw a new card? 🙂";
  } else if (sum === 21) {
    message = "Wohoo! You've got Blackjack! 🥳";
    hasBlackJack = true;
  } else {
    message = "You're out of the game! 😭";
    isAlive = false;
  }
  messageEl.textContent = message;
}

function newCard() {
  // Only allow the player to get a new card if she IS alive and does NOT have Blackjack
  if (isAlive === true && hasBlackJack === false) {
    let card = getRandomCard();
    sum += card;
    cards.push(card);
    renderGame();
  }
}

    ```
