Discord.js Rock, Paper, Scissors (Basic command handler included)

app.js

const { Client } = require('discord.js');
const client = new Client();

client.on('ready', () => {
    console.log(`Logged in as ${client.user.tag}!`);
});

const prefix = '!';

client.on('message', message => {

    if (message.author.bot) return;
    if (message.content.indexOf(prefix) !== 0) return;

    const args = message.content.slice(prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

    if (command === 'rps') {
        const acceptedReplies = ['rock', 'paper', 'scissors'];
        const random = Math.floor((Math.random() * acceptedReplies.length));
        const result = acceptedReplies[random];

        const choice = args[0];
        if (!choice) return message.channel.send(`How to play: \`${prefix}rps <rock|paper|scissors>\``);
        if (!acceptedReplies.includes(choice)) return message.channel.send(`Only these responses are accepted: \`${acceptedReplies.join(', ')}\``);
        
        console.log('Bot Result:', result);
        if (result === choice) return message.reply("It's a tie! We had the same choice.");
        
        switch (choice) {
            case 'rock': {
                if (result === 'paper') return message.reply('I won!');
                else return message.reply('You won!');
            }
            case 'paper': {
                if (result === 'scissors') return message.reply('I won!');
                else return message.reply('You won!');        
            }
            case 'scissors': {
                if (result === 'rock') return message.reply('I won!');
                else return message.reply('You won!');
            }
            default: {
                return message.channel.send(`Only these responses are accepted: \`${acceptedReplies.join(', ')}\``);
            }
        }
    }
});

client.login('TOKEN');

finally, someone who didn't use command handler

Well, I don't normally provide code examples using command handlers because it's an example. It should generally be able to fit into any context.

SyntaxError: Identifier 'client' has already been declared

SourceCode:
const client = new Client();

const prefix = 'i/';

client.on('message', message => {

if (message.author.bot) return;
if (message.content.indexOf(prefix) !== 0) return;

const args = message.content.slice(prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();

if (command === 'i/rps') {
    const acceptedReplies = ['rock', 'paper', 'scissors'];
    const random = Math.floor((Math.random() * acceptedReplies.length));
    const result = acceptedReplies[random];

    const choice = args[0];
    if (!choice) return message.channel.send(`How to play: \`${prefix}rps <rock|paper|scissors>\``);
    if (!acceptedReplies.includes(choice)) return message.channel.send(`Only these responses are accepted: \`${acceptedReplies.join(', ')}\``);
    
    console.log('Bot Result:', result);
    if (result === choice) return message.reply("It's a tie! We had the same choice.");
    
    switch (choice) {
        case 'rock': {
            if (result === 'paper') return message.reply('I won!');
            else return message.reply('You won!');
        }
        case 'paper': {
            if (result === 'scissors') return message.reply('I won!');
            else return message.reply('You won!');        
        }
        case 'scissors': {
            if (result === 'rock') return message.reply('I won!');
            else return message.reply('You won!');
        }
        default: {
            return message.channel.send(`Only these responses are accepted: \`${acceptedReplies.join(', ')}\``);
        }
    }
}

});

No longer maintaining this. It's a simple fix if you choose to learn the fundamentals of JavaScript.

That was ironically good timing to say you don't support it btw.

Uhm, hello. Im kinda new in this, I want to ask if you can make scoring system. Thanks.

Hey, If you read the previous comment, you would have read that I no longer maintain this piece of code. Also, making a scoring system for you isn't in my purview either.
