用其他字符替换某些字符

Question

我正在尝试设置我的第一个Discord机器人，以便能够用其他字母替换某些字母，但是我对使用javascript编码非常陌生。

function debunkCommand(arguments, recievedMessage) {
     if (arguments.length > 0) {
    function strReplace(){
            var myStr = argument;
            var newStr = myStr.replace(/l/gi, "w");
            var newStr = myStr.replace(/r/gi, "w");
        receivedMessage.channel.send(newStr)
    }
     } else {
    receivedMessage.channel.send("that's impossible to debunk")
      }
}

期望能够编写“！debunk hello”并让机器人发回一条消息，说“ hewwo”

Answer 1

function debunkCommand(args, receivedMessage) {
    if (args.length) {
        /*
            arguments is an array of strings, doing 'arguments.join(" ")' will join these strings into one
            /[lr]+/gi will match any instances of 'l' or 'r'

            it's also a good idea to rename your "arguments" parameter to "args", since "arguments" is already a standart js object
        */
        receivedMessage.channel.send(args.join(" ").replace(/[lr]+/gi, "w"));
     } else {
        receivedMessage.channel.send("that's impossible to debunk");
    };
};
