Rock Paper Scissors [Exercise]

In this exercise we take user input and computer input to play rock, paper, scissor and decides who wins.

Solution Code:

const getUserChoice = (userInput) => {
  userInput = userInput.toLowerCase();
  if (userInput === "rock" || "paper" || "scissors") {
    console.log(userInput);
  } else {
    console.log("Error");
  }
};

function getComputerChoice() {
  const randomNumber = Math.floor(Math.random() * 3);
  if (randomNumber === 0) {
    console.log("rock");
  } else if (randomNumber === 1) {
    console.log("paper");
  } else {
    console.log("scissor");
  }
}

// console.log(getComputerChoice());

const determineWinner = (userChoice, computerChoice) => {
  if (userChoice === computerChoice) {
    console.log("The game is a tie.");
  }
  if (userChoice === "rock") {
    if (computerChoice === "paper") {
      console.log("The computer won.");
    } else {
      console.log("The user won.");
    }
  }
  if (userChoice === "paper") {
    if (computerChoice === "rock") {
      console.log("The user won.");
    } else {
      console.log("The computer won.");
    }
  }
  if (userChoice === "scissors") {
    if (computerChoice === "paper") {
      console.log("The computer won.");
    } else {
      console.log("The user won.");
    }
  }
};

// console.log(determineWinner('scissor', 'rock'));

function playGame() {
  let userChoice = getUserChoice("rock");
  // console.log(userChoice);
  let computerChoice = getComputerChoice();
  // console.log(computerChoice);

  // console.log(determineWinner(userChoice, computerChoice));
}

playGame(); // Lets play the game
