Step by Step solution about How to resolve the algorithm Pig the dice game step by step in the JavaScript programming language

Explanation:

This JavaScript code simulates a simple dice rolling game with two players.

1. Initialization:

• It initializes an array players with two objects, each representing a player with an empty name and a score of 0.
• It initializes the current player index to 1 (second player) and gameOver to false.
• It prompts the user to enter names for each player and uppercases them.

2. Roll Function:

• The roll function simulates rolling a dice by generating a random number between 1 and 6 (inclusive).

3. Round Function:

• The round function takes a player object as an argument and simulates a round of the game for that player.
• It initializes curSum (current sum) to 0, quit to false, and dice (the rolled number) to 0.
• It alerts the player's name and current score.
• It enters a loop that continues as long as quit is false.
  • It generates a dice roll and stores it in dice.
  • If the roll is 1, it alerts the player that they rolled a 1 and quits the loop.
  • Otherwise, it adds the rolled number to curSum and asks the player if they want to roll again using a confirm.
  • If the player chooses to quit, it updates the player's score with curSum.
  • If the player's score reaches or exceeds 100, it sets gameOver to true.

4. Game Loop:

• The main game loop continues as long as gameOver is false.
• It alternates between the two players (0 and 1) and calls the round function for the current player.
• If gameOver becomes true, it alerts the winning player's name and score.

Gameplay:

The game starts with the first player taking a turn. They roll the dice, and if they roll a number other than 1, they can choose to roll again and add the rolled numbers to their score. However, if they roll a 1, they lose their turn and their current score is reset to 0. Players take turns until one of them reaches or exceeds 100 points, in which case they win the game.

let players = [
  { name: '', score: 0 },
  { name: '', score: 0 }
];
let curPlayer = 1,
    gameOver = false;

players[0].name = prompt('Your name, player #1:').toUpperCase();
players[1].name = prompt('Your name, player #2:').toUpperCase();

function roll() { return 1 + Math.floor(Math.random()*6) }

function round(player) {
  let curSum = 0,
      quit = false,
      dice;
  alert(`It's ${player.name}'s turn (${player.score}).`);
  while (!quit) {
      dice = roll();
      if (dice == 1) {
        alert('You roll a 1. What a pity!');
        quit = true;
      } else {
        curSum += dice;
        quit = !confirm(`
          You roll a ${dice} (sum: ${curSum}).\n
          Roll again?
        `);
        if (quit) {
          player.score += curSum;
          if (player.score >= 100) gameOver = true;
        }
      }
  }
}
// main
while (!gameOver) {
  if (curPlayer == 0) curPlayer = 1; else curPlayer = 0;
  round(players[curPlayer]);
  if (gameOver) alert(`
    ${players[curPlayer].name} wins (${players[curPlayer].score}).
  `);
}
