I was doing the rockPaperScissors.js project and I finished every task and got the correct output. But for some reason after the userChoice, computerChoice, and determineWinner output there is an undefined.
You threw: scissors
The computer threw: paper
You win!
undefined
I do not know where this undefined is coming from.
Here is the code:
const getUserChoice = userInput => {
userInput = userInput.toLowerCase();
if (userInput === 'rock' || userInput === 'paper' || userInput === 'scissors' || userInput === 'bomb') {
return userInput;
} else {
console.log('ERROR! Make sure you entered the correct choice.');
}
};
const getComputerChoice = () => {
randomNumber = Math.floor(Math.random() * 3);
switch (randomNumber) {
case 0:
return 'rock';
case 1:
return 'paper';
case 2:
return 'scissors';
}
};
const determineWinner = (userChoice, computerChoice) => {
if (userChoice === computerChoice) {
return 'The game ends in a tie.';
}
if (userChoice === 'rock') {
if (computerChoice === 'paper') {
return 'You lost';
} else {
return 'You won!';
}
} ;
if (userChoice === 'paper') {
if (computerChoice === 'rock') {
return 'You win!';
} else {
return 'You lost';
}
}
if (userChoice === 'scissors') {
if (computerChoice === 'paper') {
return 'You win!';
} else {
return 'You lost';
}
}
if (userChoice === 'bomb') {
return 'You win!';
}
};
const playGame = () => {
const userChoice = getUserChoice('scissors');
const computerChoice = getComputerChoice();
console.log(`You threw: ${userChoice}`);
console.log(`The computer threw: ${computerChoice}`);
console.log(determineWinner(userChoice, computerChoice));
};
console.log(playGame());
