Trying to make a really small RockPaperScissors game

Hello everyone

I have just gotten to the create a Rock, Paper, Scissors game project in the Web Development career path and I was wondering just how smaller I can make the .js file where the logic of my game is.

This is what I have so far (1.77 kb):

HTML file:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <script src="/rockpaperscissors.js" type="text/javascript"></script>
</head>
<body>
    <button id="rock" onclick="determineWinner(this.id)">Click for rock!</button>
    <button id="paper" onclick="determineWinner(this.id)">Click for paper!</button>
    <button id="scissors" onclick="determineWinner(this.id)">Click for scissors!</button>
    <p id="result"></p>
</body>
</html>

JS file:

let options = ["rock", "paper", "scissors"];

let winner = "";

let compVictories = 0;

let userVictories = 0;

 

function determineWinner(clickedId) {

    computerChoice = options[Math.floor(Math.random() * 3)];

    if (clickedId === computerChoice) { return document.getElementById("result").innerText = "This is a tie!"; }

    else if (clickedId === "rock" && computerChoice === "scissors") { winner = "User"; userVictories++;}

    else if (clickedId === "rock" && computerChoice === "paper") { winner = "Computer"; compVictories++;}

    else if (clickedId === "paper" && computerChoice === "scissors") { winner = "Computer"; compVictories++;}

    else if (clickedId === "paper" && computerChoice === "rock") { winner = "User"; userVictories++;}

    else if (clickedId === "scissors" && computerChoice === "paper") { winner = "User"; userVictories++;}

    else if (clickedId === "scissors" && computerChoice === "rock") { winner = "Computer"; compVictories++;}

    document.getElementById("result").innerText = `User has used ${clickedId}, while his opponent has used ${computerChoice}. Winner is ${winner}! 

    This bring the total victories to ${userVictories} for the user and ${compVictories} for computer.`

}

And this is how it looks:

My question is: just how much smaller in terms of memory and space you reckon I can make it?

Many thanks.
