Discord.js Errors in pay command - discord

Question

I'm facing a problem for a few days in the "pay" command in my little economy system, what I'm trying to do is, when executing the command for example "pay #user 2k" it recognizes as just "2 coins ", how can I make a shortcut to 2k answer for 2000 and so on? I'll leave the code snippet below for understanding, and if you have any ideas it will be very helpful!
const user =
this.client.users.cache.get(args[0]) || message.mentions.users.first();
const doc = await this.client.database.users.findOne({
idU: message.author.id,
});
const money = parseInt(args[1]);
if (!user)
return message.quote(
`Você deve mencionar para quem deseja enviar dinheiro.`
)
if (!money)
return message.quote(
`Você deve inserir quanto deseja enviar.`
)
if (user.id === message.author.id)
return message.quote(
`Você não pode enviar dinheiro para si mesmo.`
)
if (isNaN(money) || money <= 0)
return message.quote(`Dinheiro inválido ou não reconhecido.`);
if (money > doc.bank)
return message.quote(
`Você não me informou a quantidade de dinheiro ou não possui essa quantia!`
)
const target = await this.client.database.users.findOne({ idU: user.id });
```

Here is a little translator:
function translateNum(str) {
var nums = str.match(/[0-9]+[kmbt]/i);
if(!nums) return parseInt(str);
var check = nums[0].toLowerCase();
var num = parseInt(check);
if(check) {
var letter = check.slice(check.length-1);
if(letter === 'k') return num*1000;
if(letter === 'm') return num*1000000;
if(letter === 'b') //... until t (trillion) if you want that
return 0; //in case an error occurs
} else {
return parseInt(str);
}
}
And now just run translateNum('2k') and it should work and return 2000 instead of 2. Any errors? Tell me!
Explanation:
str would be the number string of course, and when you put str.match(), it checks for a number, or multiple numbers followed by either k, m, b or t. Then, the rest gives out different responses depending on the letter. If there is no match with str.match(), it returns the string as a number. Also, the i modifier makes it case insensitive, so you can do 2K, or 2k
