Warum fügt mein Code jedes Mal, wenn er die playRound-Funktion aufruft, zu „playerScore“ hinzu, anstatt zu „computerScore“?

In meiner Projektbeschreibung wurde vorgeschlagen, die Funktion „playRound“ fünfmal in der Funktion „Spiel“ aufzurufen, da ich nicht untersucht habe, wie man den Code „schleifen“ kann, um die Funktionsaufrufe zu wiederholen.

Mein Profil: https://www.theodinproject.com/lessons/foundations-rock-paper-scissors

Ich habe versucht, beim Aufruf der playRound-Funktion 1 zu playerScore oder computerScore hinzuzufügen (sie werden als globale Variablen mit dem Wert 0 deklariert).

Ich habe versucht, den Inkrementoperator ++ und zu verwenden Ich habe versucht, den Additionszuweisungsoperator += 1

Ich dachte, die Punktzahl des siegreichen Spielers würde um 1 erhöht.

Was tatsächlich passiert ist: Bei jedem Aufruf der playRound-Funktion wird playerScore um 1 erhöht, was nicht mit dem Gewinner übereinstimmt.

//write a program to play 'rock, paper, scissors' game against the computer

//COMPUTER CHOICE- generate random choice of weapon
let choice = ['rock', 'paper', 'scissors'];
//select random array element from weapon array
function getComputerChoice() {
  computerChoice = choice[(Math.floor(Math.random() * choice.length))];
  return computerChoice;
}


//USER CHOICE- assign user choice from prompt input
function getPlayerChoice() {
  playerChoice = prompt('Choose your weapon', 'rock, paper or scissors?');
  return playerChoice;
}


//assign values to player variables 
const playerSelection = getPlayerChoice().toLowerCase();
const computerSelection = getComputerChoice();


//message to return to player
let youWin = `You win, ${playerSelection} beats ${computerSelection}`;
let youLose = `You lose, ${computerSelection} beats ${playerSelection}`;
let youDraw = `It's a draw!`;
//put message options into an array
let message = [youWin, youLose, youDraw];


//make global player score variables
let playerScore = 0;
let computerScore = 0;


//function to play one round
function playRound() {

  if (playerSelection == computerSelection) {
    return youDraw;
  } else if (playerSelection == 'rock' && computerSelection == 'paper') {
    computerScore = computerScore++;
    return message[1]; //you lose
  } else if (playerSelection == 'rock' && computerSelection == 'scissors') {
    playerScore++;
    return message[0]; //you win
  } else if (playerSelection == 'paper' && computerSelection == 'rock') {
    playerScore++;

    playerScore++;
    return message[0]; //you win
  } else {
    return ('oops! Type rock, paper or scissors!')
  }
}


//function to play five rounds and report player as winner or loser at the end

  //check code: what values are assigned to player selections?
  console.log('player ', playerSelection);
  console.log('computer ', computerSelection);

  playRound();
  playRound();
  playRound();
  playRound();

  return playRound();
}

console.log(game());

console.log(playerScore);
