const looksLikeACreditCard = match("^[0-9]{4}-[0-9]{4}-[0-9]{4}-[0-9]{4}$|^[0-9]{4} [0-9]{4} [0-9]{4} [0-9]{4}$");


const validate = or(

          isNumber,
          len(16)
        ),
        and(

          looksLikeACreditCard
        )
    )


const test1 = validate(4534567890123456); // true
const test2 = validate("4534 5678 9012 3456"); // true

const test3 = validate(453456789012345); // false number with less than 16 digits
const test4 = validate("4534 5678 9012 34"); // false: string with the wrong format
