How do a get a function to recognize a return value from other function in javascript?

Question

I started learning to code recently, and following a program called Odin Project. I'm currently tring to make a Rock, Paper Scissor games, but I got stuck. I created a function to to make the computer choose a random value among the three options and return one of them. Then I created another function to alert a different message according to the computerchoice. But I always get the message "Something went wrong", which means this new function is not getting any of the correct options from the previous one. Can anybody help?

// THIS FUNCTION DECIDES IF THE COMPUTER CHOOSES ROCK, PAPER OR SCISSOS
function getComputerChoice () {
    var rand = Math.floor(Math.random() * 10);
    if (rand <= 3) {
        return "Rock"
    } else if (rand <= 6) {
        return "Paper"
    } else {
        return "Scissors"
}}

// I PUT THE COMPUTER CHOICE FUNCTION IN A CONST BOX
const computerSelection = getComputerChoice();

// TESTING PLAYROUND FUNCTION
function playRound(computerSelection) { 
        if (computerSelection === "Paper") {
        alert("You lose! Paper beats Rock")
    } else if (computerSelection === "Rock") {
        alert("Draw")
    } else if (computerSelection === "Scissors") {
        alert("You win!")
    } else {
        alert("Something went wrong")
    }
  }
   
   

function game() {
    for (let i = 0; i < 2 ; i++) {
        // your code here!
        playRound();
     }
}

game();

Move the line const computerSelection = getComputerChoice(); into the function playRound() and get rid of the parameter of that function:

 // THIS FUNCTION DECIDES IF THE COMPUTER CHOOSES ROCK, PAPER OR SCISSOS function getComputerChoice() { var rand = Math.floor(Math.random() * 10); if (rand <= 3) { return "Rock" } else if (rand <= 6) { return "Paper" } else { return "Scissors" } } // TESTING PLAYROUND FUNCTION function playRound() { // I PUT THE COMPUTER CHOICE FUNCTION IN A CONST BOX const computerSelection = getComputerChoice(); if (computerSelection === "Paper") { alert("You lose; Paper beats Rock") } else if (computerSelection === "Rock") { alert("Draw") } else if (computerSelection === "Scissors") { alert("You win;") } else { alert("Something went wrong") } } function game() { for (let i = 0; i < 2; i++) { // your code here! playRound(); } } game();
