Discordjs args check if its a word

Question

im making a bot to get bitcoin price and also exchange it from discord. I want to check if args[0] it is a number, if not to return and send a message.

        if (!args.length){
            return message.channel.send(`${message.author} You need to input arguments, example: -exchange 15000`);
        }


        const url = `https://blockchain.info/tobtc?currency=USD&value=${args[0]}`;

        request(url, (err, res, body) => {

`isNaN(args[0])` will be true if `args[0]` is NOT a number.. try that — The Bomb Squad, Nov 25 '20 at 13:53
Maybe `if (isNaN(args[0])) { return message.channel.send('You need to input a number not a letter'); }`. — ThRnk, Nov 25 '20 at 14:12

use args[0] instead of args.length
if you use args with if(args) it will return a Boolean
so your code should be like this :

if (!args[0]){
  return message.channel.send(`${message.author} You need to input arguments, example: -exchange 15000`);
}
