格式化货币

const formatMoney = (money) => {
  return money.replace(new RegExp(`(?!^)(?=(\\d{3})+${money.includes('.') ? '\\.' : '$'})`, 'g'), ',')  
}

formatMoney('123456789') // '123,456,789'
formatMoney('123456789.123') // '123,456,789.123'
formatMoney('123') // '123'

or

const formatMoney = (money) => {
  return money.toLocaleString()
}

formatMoney(123456789) // '123,456,789'
formatMoney(123456789.123) // '123,456,789.123'
formatMoney(123) // '123'
