Here’s my code for the Rock, Paper, or Scissors project:
Hey everyone!
After hours of checking for errors 1000 times, which ended up being misplaced semicolons, curly brackets and typos 
, I wanted to share my code for other desperate souls out there:
const getUserChoice = userInput => {
userInput = userInput.toLowerCase();
if (userInput === 'rock') {
return userInput;
} else if (userInput === 'paper') {
return userInput;
} else if (userInput === 'scissors') {
return userInput;
} else if (userInput === 'bomb') {
return userInput;
} else {
console.log('Input not valid!');
}
};
const getComputerChoice = () => {
const randomNumber = Math.floor(Math.random() * 3);
switch (randomNumber) {
case 0:
return 'rock'
break;
case 1:
return 'paper'
break;
case 2:
return 'scissors'
break;
}
};
const determineWinner = (userChoice, computerChoice) => {
if (userChoice === computerChoice) {
return 'The game is a tie!';
}
if (userChoice === 'bomb') {
if (computerChoice === 'rock' || computerChoice === 'paper' || computerChoice === 'scissors') {
return 'You\'re the BOMB!';
}
}
if (userChoice === 'rock') {
if (computerChoice === 'paper') {
return 'The computer has won!';
} else {
return 'Congratulations, you won!';
}
}
if (userChoice === 'paper') {
if (computerChoice === 'scissors') {
return "Sorry, computer won!";
} else {
return "Congratulations, you won!";
}
}
if (userChoice === 'scissors') {
if (computerChoice === 'rock') {
return 'Sorry, computer wins!';
} else {
return 'Congratulations, you won!';
}
}
};
const playGame = () => {
const userChoice = getUserChoice('bomb');
const computerChoice = getComputerChoice();
console.log('You threw: ' + userChoice);
console.log('The computer threw: ' + computerChoice);
console.log(determineWinner(userChoice, computerChoice));
};
playGame();
Thank you very much for all the support on this forum and walkthrough videos!
Best regards,

Hey Cristina
I see that the user choice is hard coded to bomb. Why don’t you set it randomly instead, this way every time the code run the result is going to be unexpected.
Hey,
sorry but I don’t know exactly what you mean.
Here “bomb” was supposed to be like a “cheat code” to beat the computer. Making it random would defeat the purpose no?
I’m a newbie so maybe I didn’t fully understand :)).
Thanks for your reply.
Hey,
well I think it would be nice to see every time a different result. The purpose of the cheat is not defeated anyhow, because it’s available only to the player, with a random choice the player still has about 25% (1 out of 4 possible choices) to certainly win, whatever is the choice of the computer.
Does this make sense?
Hmm, you mean like this?
const getUserChoice = () => {
const randomChoice = Math.floor(Math.random() * 4);
switch (randomChoice) {
case 0:
return 'rock'
break;
case 1:
return 'paper'
break;
case 2:
return 'scissors'
break;
case 3:
return 'bomb'
break;
}
}
const getComputerChoice = () => {
const randomNumber = Math.floor(Math.random() * 3);
switch (randomNumber) {
case 0:
return 'rock'
break;
case 1:
return 'paper'
break;
case 2:
return 'scissors'
break;
}
};
const determineWinner = (userChoice, computerChoice) => {
if (userChoice === computerChoice) {
return 'The game is a tie!';
}
if (userChoice === 'bomb') {
if (computerChoice === 'rock' || computerChoice === 'paper' || computerChoice === 'scissors') {
return 'You\'re the BOMB!';
}
}
if (userChoice === 'rock') {
if (computerChoice === 'paper') {
return 'The computer has won!';
} else {
return 'Congratulations, you won!';
}
}
if (userChoice === 'paper') {
if (computerChoice === 'scissors') {
return "Sorry, computer won!";
} else {
return "Congratulations, you won!";
}
}
if (userChoice === 'scissors') {
if (computerChoice === 'rock') {
return 'Sorry, computer wins!';
} else {
return 'Congratulations, you won!';
}
}
};
const playGame = () => {
const userChoice = getUserChoice();
const computerChoice = getComputerChoice();
console.log('You threw: ' + userChoice);
console.log('The computer threw: ' + computerChoice);
console.log(determineWinner(userChoice, computerChoice));
};
playGame();
So, instead of having a user input, you have a random choice, as with the computer?
Hope I got it right :))
Yeah I meant that. Cool, I won 2 out of 5, 2 ties and 1 lose, not bad 
Have you played it?
Yeah, very exciting :))
