How can I take varying amount of arguments?

So I have this Discord bot with a command to add a link/password combo. Currently it can only accept two arguments, but I have users who would like to paste in a whole list of links/passwords and have them all entered at once.

This is my code now:

if (command === "add"){
message.delete();
let link = message.content.split(" ")[1];
let answer = message.content.split(" ")[2];
  if (!link || !answer){
  user.send('Please be sure to enter a link **and** its corresponding answer.');
  }
lockers.push({"link":link,"answer":answer});
fs.writeFile('./serverLockers.json', JSON.stringify(serverLockers), (err) => {if(err) console.error(err)});
return;
}

The message in this case would be string that is "[command] [link] [answer]".

I want to be able to do something like "[command] [link] [answer],[link] [answer],[link] [answer]"

How can I change this to add multiple combos at once? It will have to know how many combinations were entered And the amount of combinations entered will always vary
