Он говорит, что ожидается объект line one char 1, но нет ни одной ошибки, что мне делать?

function userChoice = prompt("Do you want to choose rock, paper or scissors?");
if (userChoice !== "rock" || userChoice !== "paper" || userChoice !== "scissors") {
    console.log("Invalid choice. Please choose rock, paper or scissors.")
    prompt("Do you want to choose rock, paper or scissors?");
}
console.log("Player: " + userChoice);

var computerChoice = Math.random();
if (computerChoice < 0.34) {
    computerChoice = "rock";
}
else if (computerChoice <= 0.67){
    computerChoice = "paper";
}
else {
    computerChoice = "scissors";
}
console.log("Computer: " + computerChoice);

function compare(choice1, choice2){
    if (choice1 === choice2) {
        console.log("The result is a tie");
    }
    else if (choice1 === "rock") {
        if (choice2 === "scissors") {
            console.log("rock wins!");
        }
        else {
            console.log("paper wins!");
        }
    }
    else if (choice1 === "paper") {
        if (choice2 === "scissors") {
            console.log("scissors win!");
        }
        else {
            console.log("paper wins!");
        }
    }
};
compare(userChoice, computerChoice);

Что я уже пробовал:

var userChoice = prompt("Do you want to choose rock, paper or scissors?");
if (userChoice !== "rock" || userChoice !== "paper" || userChoice !== "scissors") {
    console.log("Invalid choice. Please choose rock, paper or scissors.")
    prompt("Do you want to choose rock, paper or scissors?");
}
console.log("Player: " + userChoice);

var computerChoice = Math.random();
if (computerChoice < 0.34) {
    computerChoice = "rock";
}
else if (computerChoice <= 0.67){
    computerChoice = "paper";
}
else {
    computerChoice = "scissors";
}
console.log("Computer: " + computerChoice);

function compare(choice1, choice2){
    if (choice1 === choice2) {
        console.log("The result is a tie");
    }
    else if (choice1 === "rock") {
        if (choice2 === "scissors") {
            console.log("rock wins!");
        }
        else {
            console.log("paper wins!");
        }
    }
    else if (choice1 === "paper") {
        if (choice2 === "scissors") {
            console.log("scissors win!");
        }
        else {
            console.log("paper wins!");
        }
    }
};
compare(userChoice, computerChoice);
