How to use it:

import { 
  isValid, 
  isExpirationDateValid, 
  isSecurityCodeValid, 
  getCreditCardNameByNumber 
} from 'creditcard.js';

2. Or include the credicard.js script on your webpage.

<script src="/dist/creditcard.min.js"></script>

// OR From A CDN
<script type="module">
  import creditcardJs from 'https://cdn.jsdelivr.net/npm/creditcard.js@3.0.27/+esm'
</script>

3. Validate a specified credit card number.

var creditcard = new CreditCard();
// return true
console.log(creditcard.isValid('4111111111111111'));
isValid('4916108926268679', { cards: ['visa', 'mastercard'] }) // returns true
isValid('4916108926268679', { cards: ['mastercard'] }) // returns false

4. Validate the expiration date.

var creditcard = new CreditCard();
// return true
console.log(creditcard.isExpirationDateValid(''05', '2020''));

5. Validate the security code.

var creditcard = new CreditCard();
// return true
console.log(creditcard.isSecurityCodeValid(''4111111111111111', '250''));

6. Validate a specified credit card number and return the result in the console.log.
