How do I make an "Invalid Command" message when someone types an unknown command in Discord.js?

I've searched everywhere to find a small piece of code that tells the user that the command they entered does not exist.

I found this, but I don't understand it, can someone explain (or simplify)?

My code is here.

Solution

  • Place the acceptable commands into an array.

    e.g:

    let userInputCommand = getUserInputCommand();

let validCommands = ["command1", "command2", "command3"];

let isValid = validCommands.includes(userInputCommand);

if(!isValid) {
  return message.channel.send("Please enter a valid command!");
}

    Use .includes() to see if the command exists. (getUserInputCommand() is just an example, not referring to your actual code.)
