Rock, Paper, Scissors Project -- Can someone help me figure out why I have undefined being produced in my output

Hi everyone, I am new to JavaScript and 3 days fresh in. I only have prior experience with Python 3 prior to this. Could anyone tell me if I have improper indentation or syntax of some sort in my code, causing for an undefined to appear.

rockPaperScissors.js

const getUserChoice = userInput => {
  userInput = userInput.toLowerCase();
  if (userInput == 'rock' || userInput == 'paper' || userInput == 'scissors' || userInput == 'bomb') {
    return userInput
} else {
  console.log('Error, Please type in rock, paper, or scissors.')
}
}
const getComputerChoice = () => {
  const randomNumber = Math.floor(Math.random() * 4);

Hello @ale_eck, welcome to the forums! The undefined is coming from the fact that you console.log your playGame() function, but that function doesn’t return anything. This means that JavaScript automatically returns undefined, which is then printed when you log the function.
