Rock, Paper, Scissors game in Javascript

I am making a Rock paper, and scissors game for the Odin project which is supposed to run in the console.
Currently, everything works fine until I implemented the function called game().
I assumed it would call the playRound() function until playerscore, or computerscore reached 5. but it is currently only working twice. It prompts once up top for playerSelection and prompts again for playerSelection within function game();
How could I get game() to run until either playerscore or computerscore reaches 5? And display result for each round?
let playerScore = 0;
let computerScore = 0;
function computerPlay() {
let choices = ['rock', 'paper', 'scissors']
return choices[Math.floor(Math.random() * choices.length)]
}
let computerSelection = computerPlay();
let playerSelection = prompt("Make your selection, Rock, paper or Scissors").toLowerCase();
function playRound(playerSelection, computerSelection){
if ((playerSelection == "rock" && computerSelection == "scissors") ||
(playerSelection == "scissors" && computerSelection == "paper") ||
(playerSelection == "paper" && computerSelection == "rock")){
playerScore++;
return ("You win! " + playerSelection + " beats " + computerSelection + ", the score is Player:" + playerScore + " Computer:" + computerScore);
} else if (playerSelection == computerSelection){
return "Draw!"
} else {
computerScore++
return ("You lose! " + computerSelection+ ", beats " + playerSelection + " the score is Player:" + playerScore + " Computer:" + computerScore)
}
}
function game(){
if (playerScore < 5 && computerScore < 5) {
let playerSelection = prompt("Make your selection, Rock, paper or Scissors").toLowerCase();
playRound(playerSelection, computerSelection)
}
}
game();
console.log(playRound(playerSelection,computerSelection));

My code is not running but i have no errors

The project is about making a rock paper scissors game using functions and loops etc.
the code below is how the project looks
the first function is to get the randomized computer choice
the second function is to get the user or players choice
the third function is to play the game and check if the player won or the computer won
the final function is to create a for loop to run the third function a certain number of times to see who is the winner of the game
Been working on it since and have no idea why it doesn't work
```
function getComputerChoice() {
let values = ["rock", "paper", "scissors"];
return values[Math.floor(Math.random() * values.length)];
}
function getPlayerChoice() {
let getChoice = "rock";
let value = getChoice.trim();
let lowCase = value.toLowerCase();
let capitalize = lowCase.charAt(0).toUpperCase + lowCase.slice(1);
while (!["Rock", "Paper", "Scissors"].includes(capitalize)) {
value = getChoice.trim();
lowCase = value.toLowerCase();
capitalize = lowCase.charAt(0).toUpperCase + lowCase.slice(1);
}
return capitalize;
}
function playRound(playerSelection, computerSelection) {
let games = "";
if (
(playerSelection == "rock" && computerSelection == "paper") ||
(playerSelection == "paper" && computerSelection == "scissors") ||
(playerSelection == "scissors" && computerSelection == "rock")
) {
return (games =
"player loses!! " + computerSelection + " beats " + playerSelection);
} else if (
(playerSelection == "paper" && computerSelection == "rock") ||
(playerSelection == "scissors" && computerSelection == "paper") ||
(playerSelection == "rock" && computerSelection == "scissors")
) {
return (games =
"player Wins!! " + playerSelection + " beats " + computerSelection);
} else if (playerSelection == computerSelection) {
return (games =
"it a tie noice " + playerSelection + " v " + computerSelection);
} else {
return (games = "euphoria");
}
}
function game() {
let playerScores = 0;
let computerScores = 0;
let computerSelection = "";
let playerSelection = "";
computerSelection = getComputerChoice();
playerSelection = getPlayerChoice();
for (let i = 0; i < 5; i++) {
if (
playRound(
"player loses!! " + computerSelection + " beats " + playerSelection
)
) {
computerScores += 1;
console.log(
"you lost this round!! boo hoo!! scores are " +
computerScores +
" v " +
playerScores
);
} else if (
playRound(
"player Wins!! " + playerSelection + " beats " + computerSelection
)
) {
playerScores += 1;
console.log(
"you Won this round!! hurray!! scores are " +
computerScores +
" v " +
playerScores
);
}
}
if (playerScores > computerScores) {
console.log("congratulations you won this round");
} else if (playerScores < computerScores) {
console.log("im sorry you lost this round");
} else {
console.log("there is a problem");
}
}
game();
```

It doesn't seem that playRound() is returning anything:
function playRound(playerSelection, computerSelection) {
let games = '';
if (
(playerSelection == "rock" && computerSelection == "paper") ||
(playerSelection == "paper" && computerSelection == "scissors") ||
(playerSelection == "scissors" && computerSelection == "rock")
) {
games = "player loses!! " + computerSelection + " beats " + playerSelection;
// ADD RETURN HERE
} else if (
(playerSelection == "paper" && computerSelection == "rock") ||
(playerSelection == "scissors" && computerSelection == "paper") ||
(playerSelection == "rock" && computerSelection == "scissors")
) {
games = "player Wins!! " + playerSelection + " beats " + computerSelection;
// ADD RETURN HERE
} else if (playerSelection == computerSelection) {
games = "it a tie noice " + playerSelection + " v " + computerSelection;
// ADD RETURN HERE
} else {
games = "euphoria";
// ADD RETURN HERE
}
}
Explanation
In your game() function definition you are checking if(playRound()). playRound is not returning anything so this is interpreted as a void function, hence, the if will always evaluate to false.

Can anyone tell me why my code doesn't work properly? Game ROCK, PAPER, SCISSORS. Java Script

Can anyone tell me why my code doesn't work properly? I'm trying to make game ROCK, PAPER, SCISSORS on plain Java Script. For some reason it doesn't work as I expect.
const computerAanswer = ["rock", "paper", "scissors"];
function computerPlay() {
let answer = computerAanswer[Math.floor(Math.random() * computerAanswer.length)];
return answer;
}
console.log('computer choice is: ' + computerPlay().toUpperCase());
function playRound (playerSelection, computerSelection) {
playerSelection = playerSelection.toLowerCase()
if (playerSelection == "rock" && computerSelection == "scissors") {
return "Congrats,you are winner!";
} else if (playerSelection == "paper" && computerSelection == "rock") {
return "Congrats,you are winner!";
} else if (playerSelection == "scissors" && computerSelection == "paper") {
return "Congrats,you are winner!";
} else if (playerSelection == "rock" && computerSelection == "rock") {
return "Draw!";
} else if (playerSelection == "paper" && computerSelection == "paper") {
return "Draw!";
} else if (playerSelection == "scissors" && computerSelection == "scissors") {
return "Draw!";
} else {
return "You lose. Maybe next time...";
}
}
let playerSelection = prompt("Make your choose: Rock, Paper or Scissors?");
let computerSelection = computerPlay();
console.log(playRound(playerSelection, computerSelection));
console.log('player choice is: ' + playerSelection.toUpperCase());

I guess that's just your first console.log :
console.log('computer choice is: ' + computerPlay().toUpperCase());
It plays a round for computer, then you play another one against prompted user.
Do that instead :
function computerPlay() {
let answer = computerAanswer[Math.floor(Math.random() * computerAanswer.length)];
console.log('computer choice is: ' + answer.toUpperCase());
return answer;
}

When I nested
console.log('computer choice is: ' + answer.toUpperCase());
into computerPlay function it works.
const computerAanswer = ["rock", "paper", "scissors"];
function computerPlay() {
let answer = computerAanswer[Math.floor(Math.random() * computerAanswer.length)];
console.log('computer choice is: ' + answer.toUpperCase());
return answer;
}
function playRound (playerSelection, computerSelection) {
playerSelection = playerSelection.toLowerCase()
if (playerSelection == "rock" && computerSelection == "scissors") {
return "Congrats,you are winner!";
} else if (playerSelection == "paper" && computerSelection == "rock") {
return "Congrats,you are winner!";
} else if (playerSelection == "scissors" && computerSelection == "paper") {
return "Congrats,you are winner!";
} else if (playerSelection == "rock" && computerSelection == "rock") {
return "Draw!";
} else if (playerSelection == "paper" && computerSelection == "paper") {
return "Draw!";
} else if (playerSelection == "scissors" && computerSelection == "scissors") {
return "Draw!";
} else {
return "You lose. Maybe next time...";
}
}
let playerSelection = prompt("Make your choose: Rock, Paper or Scissors?");
let computerSelection = computerPlay();
console.log(playRound(playerSelection, computerSelection));
console.log('player choice is: ' + playerSelection.toUpperCase());

What can i do to made "Rock, papper, scissors" work?

i'm very new to js, and it's my first code on it. i'm trying to make a game "rock, papper, scissors". please, look at my code, my funcrion playRound doesn't wor, i need it to return scores.
please, give me advises how to change my code, but i don't want you to solve all for me. thank you.
function computerPlay() {
let computerAction = Math.floor(Math.random() * choises.length);
let computerSelection = choises[computerAction];
return computerSelection;
}
function userPlay() {
let playerSelection = prompt(choises).toLowerCase();
return playerSelection;
}
let choises = ['rock', 'paper', 'scissors'];
let Score = new Map([
['userScores', 0],
['computerScores', 0]
]);
function playRound(playerSelection, computerSelection) {
if (playerSelection === choises[0] && computerSelection === choises[0]) ||
(playerSelection === choises[1] && computerSelection === choises[1]) ||
(playerSelection === choises[2] && computerSelection === choises[2]){
return Score = ['userScores' + 1, 'computerScores' + 1];
} else if (playerSelection === choises[0] && computerSelection !== choises[0]) ||
(playerSelection === choises[1] && computerSelection !== choises[1]) ||
(playerSelection === choises[2] && computerSelection !== choises[2])
return Score = ['userScores' + 1, 'computerScores'];
} else if (playerSelection !== choises[0] && computerSelection === choises[0]) ||
(playerSelection !== choises[1] && computerSelection === choises[1]) ||
(playerSelection !== choises[2] && computerSelection === choises[2])
{
return Score = ['userScores', 'computerScores' + 1];
}
}

Refer to this:
function computerPlay() {
let computerAction = Math.floor(Math.random() * choises.length);
let computerSelection = choises[computerAction];
return computerSelection;
}
function userPlay() {
let playerSelection = prompt(choises).toLowerCase();
return playerSelection;
}
let choises = ['rock', 'paper', 'scissors'];
let Score = {
user: 0,
computer: 0
}
function playRound(playerSelection, computerSelection) {
if (playerSelection === computerSelection){
Score.user = Score.user + 1;
Score.computer = Score.computer + 1;
} else if ((playerSelection === choises[0] && computerSelection === choises[2]) ||
(playerSelection === choises[1] && computerSelection === choises[0]) ||
(playerSelection === choises[2] && computerSelection === choises[1])) {
Score.user = Score.user + 1;
} else {
Score.computer = Score.computer + 1;
}
}
let computerChoice = computerPlay();
let userChoice = userPlay();
playRound(userChoice, computerChoice);
console.log('computer hand', computerChoice);
console.log('user hand', userChoice);
console.log(Score);

Why is my Rock Paper Scissors game not working? It keeps returning 'You chose Rock, you win', how do i fix this?

I have been stuck on this for so long, basically its a human vs computer, I type in say Rock and it gives me you chose rock you win, even when i chose the others it still returns that, can someone help me to figure out why it keeps doing this?
let person = prompt ("Rock, Paper, Scissors");
// Computer makes a choice
function computerPlay () {
let compchoice = ['Rock', 'Paper', 'Scissors'];
return compchoice[Math.floor(Math.random() *
compchoice.length)];
}
//Player vs Computer
function playRound (playerSelection, computerSelection) {
if (playerSelection === 'Rock' || computerSelection ===
'Scissors') {
return 'You chose ' + playerSelection + ',' + ' You win!';
} else if (playerSelection === 'Paper' || computerSelection ===
'Rock')
{
return 'You chose ' + playerSelection + ',' + ' You win!';
} else if (playerSelection === 'Scissors' || computerSelection ===
'Paper')
{
return 'You chose ' + playerSelection + ',' + ' You win!';
} else if (computerSelection === 'Rock' || playerSelection ===
'Scissors')
{
return 'Computer chose ' + computerSelection + ',' + 'Computer
wins!';
} else if (computerSelection === 'Paper' || playerSelection ===
'Rock')
{
return 'Computer chose ' + computerSelection + ',' + 'Computer
wins!';
} else if (computerSelection === 'Scissors' || playerSelection ===
'Paper')
{
return 'Computer chose ' + computerSelection + ',' + 'Computer
wins!';
} else if (computerSelection === playerSelection) {
return 'Its a draw!';
}else {
return 'Please chose Rock, Paper, or Scissors';
}
}
const playerSelection = 'rock';
const computerSelection = computerPlay();
console.log(playRound(playerSelection, computerSelection));
It should just play a regular game of rock paper scissors, if i chose rock and the computer chose paper the computer should win. For now i am trying to make it play just one round.

You're using or statements. You need to use and statements. Take for example your first line:
if (playerSelection === 'Rock' || computerSelection === 'Scissors') {
return 'You chose ' + playerSelection + ',' + ' You win!';
}
It's saying:
if playerSelection equals Rock OR computerSelection equals Scissors return
So if playerSelection is Rock it'll return right there. What you need to use is an AND statement instead. Try this:
let playerSelection = prompt("Rock, Paper, Scissors");
// Computer makes a choice
function computerPlay() {
let compchoice = ['Rock', 'Paper', 'Scissors'];
return compchoice[Math.floor(Math.random() * compchoice.length)];
}
//Player vs Computer
function playRound(playerSelection, computerSelection) {
if (playerSelection === 'Rock' && computerSelection === 'Scissors') {
return 'You chose ' + playerSelection + ',' + ' You win!';
} else if (playerSelection === 'Paper' && computerSelection === 'Rock') {
return 'You chose ' + playerSelection + ',' + ' You win!';
} else if (playerSelection === 'Scissors' && computerSelection === 'Paper') {
return 'You chose ' + playerSelection + ',' + ' You win!';
} else if (computerSelection === 'Rock' && playerSelection === 'Scissors') {
return 'Computer chose ' + computerSelection + ',' + 'Computer wins!';
} else if (computerSelection === 'Paper' && playerSelection === 'Rock') {
return 'Computer chose ' + computerSelection + ',' + 'Computer wins!';
} else if (computerSelection === 'Scissors' && playerSelection === 'Paper') {
return 'Computer chose ' + computerSelection + ',' + 'Computer wins!';
} else if (computerSelection === playerSelection) {
return 'Its a draw!';
} else {
return 'Please chose Rock, Paper, or Scissors';
}
}
//const playerSelection = 'Rock';
const computerSelection = computerPlay();
console.log(playRound(playerSelection, computerSelection));
Also there was a typo in your player selection on the third last line. The playerSelection string should be capitalized like the strings it's comparing too.
