I'm pretty new to the development world, I wanted to practice doing JS, and I learned that Discord bots could be done in this language, I found it cool to practice.

My problem: I want to separate the mand from the rest of the message. I managed to separate the mand from a word, but when I enter several words, it does not work. This is what it does:

(!Command HELLO" will send "Command + Hello", but "!mand HELLO HI" will not work)

const PREFIX = "!";
bot.on('message', function(message) {
	if(message.content[0] === PREFIX) {
		let splitMessage = message.content.split(" ");
		if(splitMessage[0] === '!mand') {
			if(splitMessage.length === 2) {
				message.channel.send('Command + ' + splitMessage[1]);
			}
		}
	}
});

• Use indexOf() to find the first occurence of whitespace and substring() to grab everything after the first whitespace – Ryan Wilson Commented Feb 20, 2018 at 16:33
• It is not clear what should be the result for mand HELLO HI. You should send two mands? Or a mand with two parameters? – Rafael Paulino Commented Feb 20, 2018 at 16:34

As I stated in the ment:

    const PREFIX = "!";
    bot.on('message', function(message) {
        if(message.content[0] === PREFIX) {
            let mand = message.content.substring(message.content.indexOf(" ") + 1, message.content.length);
            message.channel.send('Command + ' + mand);
        }
    });

 splitMessage[1]

that takes the second word from the splitted array. So with Command! Hello world it will be Hello. You might want to take everything after the first element from the split Message like so:

splitMessage.slice(1)

that returns ["Hello", "World"], so you just need to join it back to a string

 .join(" ")

---

How i would do that:

  const [mand, ...args] = message.content.split(" ");

  switch(mand){
    case "!Command":
       message.channel.send('Command + ' + args.join(" "));
    break;
    //....
  }
