javascript - How can I remove characters from message

Question

I would like to take a command that takes in an input from the user let's say ".result 123" with .result being the bot command and only writing out the string after it. I've tried regex but haven't been successful. This is the code I tried:

Note: Some variables are for me to check the time for when the command is still valid.

let userinput = new RegExp('.+');
if(message.content === ".result" + userinput) {
    
    function removeCharacters() {
      message.content = str;
      str = str.substr(8);
      console.log(str); 
    }

    if ((currseconds - seconds) <= 1200) {
      message.channel.send('**FINAL RECORDED FPM:**');
      removeCharacters();
    }
}

Answer 1

There are several things wrong

• You are declaring a function inside the if, that is a bit weird
• You need to escape a dot in regex,

To find 123 in .result 123 you could do

const message = { "content": ".result 123" } // test message for this script
const userInput = message.content.match(/.result (w+)/)
if (userInput) console.log(userInput[1]); // contains the command
