如何让我的 discord 机器人通过回复池回复特定消息？

Question

Pretty much all in the title. I want my bot to respond with a random reply from a pool of replies. This is what I have so far:

const Discord = require('discord.js');
const bot = new Discord.Client();

bot.on('ready', () =>{
    console.log('Just Chillin');
    bot.user.setActivity('Working' , { type: 'BotOn'}).catch(console.error);

}); 

function randomMessage(){
    var randomNumber = Math.round(Math.random()*2); // 0, 1 or 2
    switch(randomNumber){
        case 0: return 'Hello!';
        case 1: return 'Hi!';
        case 2: return 'Hola';
    }
}

bot.on('message' , message => {
    if(message.content.toLowerCase().includes('ping'))
        message.reply('pong')
    else if(message.content.toLowerCase().includes('Hello'))
            message.reply(randomMessage());
});

Also, I do not have much experience in Java, only R, so I was also wondering where you would put the first chunk of code. Would you put it below or above the bot.on('message', message=> ? Also, when I have that code entered, nothing happens and everything else runs fine.

Thank you in advance. I apologize for my lack of Java knowledge.

When I want pick a random message (like 8ball), I always do it this way:

Define different options:

let options = ["Hey", "Hello there!", "Hey, it's me!", "NOT NOW IM BUSY"];

Pick a random message:

let result = options[Math.floor(Math.random() * options.length)];

Log the result:

console.log(result);
