**isBoolean(str [, options])** | check if a string is a boolean.
`options` is an object which defaults to `{ loose: false }`. If loose is is set to false, the validator will strictly match ['true', 'false', '0', '1']. If loose is set to true, the validator will also match 'yes', 'no', and will match a valid boolean string of any case. (eg: ['true', 'True', 'TRUE']).
**isBtcAddress(str)** | check if the string is a valid BTC address.
**isByteLength(str [, options])** | check if the string's length (in UTF-8 bytes) falls in a range.
`options` is an object which defaults to `{min:0, max: undefined}`.
-**isCreditCard(str)** | check if the string is a credit card.
+**isCreditCard(card, [, options])** | check if the string is a credit card.

Valid values include `amex` , `dinersclub` , `discover` , `jcb` , `mastercard` , `unionpay` , `visa` or blank will check for any provider.
**isCurrency(str [, options])** | check if the string is a valid currency amount.
`options` is an object which defaults to `{symbol: '$', require_symbol: false, allow_space_after_symbol: false, symbol_after_digits: false, allow_negatives: true, parens_for_negatives: false, negative_sign_before_digits: false, negative_sign_after_digits: false, allow_negative_sign_placeholder: false, thousands_separator: ',', decimal_separator: '.', allow_decimal: true, require_decimal: false, digits_after_decimal: [2], allow_space_after_digits: false}`.
**Note:** The array `digits_after_decimal` is filled with the exact number of digits allowed not a range, for example a range 1 to 3 will be given as [1, 2, 3].
**isDataURI(str)** | check if the string is a [data uri format](https://developer.mozilla.org/en-US/docs/Web/HTTP/data_URIs).
**isDate(input [, options])** | Check if the input is a valid date. e.g. [`2002-07-15`, new Date()].
`options` is an object which can contain the keys `format`, `strictMode` and/or `delimiters`
`format` is a string and defaults to `YYYY/MM/DD`.
`strictMode` is a boolean and defaults to `false`. If `strictMode` is set to true, the validator will reject inputs different from `format`.
`delimiters` is an array of allowed date delimiters and defaults to `['/', '-']`.
