Now you can handle money without headaches!

import Wallet, { Money } from 'walletjs'

const money = Money.init(100)
const wallet = Wallet.init(money)

console.log(brlWallet.getAmount('BRL')) => '100.00'
console.log(brlWallet.getAmount('USD')) => '0.00'

console.log(usdWallet.getAmount('BRL')) => '0.00'
