Discord.js |如何使您可以在变量中包含文本的情况下运行命令？

const prefix = "!";
const command = "hello";
const message = `${prefix}${command}`;
console.log(message); // 输出: !hello

const prefix = "!";
const command = "hello";
const message = prefix + command;
console.log(message); // 输出: !hello

const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = "!";

client.on('message', message => {
  if (!message.content.startsWith(prefix) || message.author.bot) return;

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

  if (command === 'hello') {
    message.channel.send('Hello, World!');
  }
});

client.login('your-token');
