**isJWT(str)** | check if the string is valid JWT token.
**isLatLong(str [, options])** | check if the string is a valid latitude-longitude coordinate in the format `lat,long` or `lat, long`.<br/><br/>`options` is an object that defaults to `{ checkDMS: false }`. Pass `checkDMS` as `true` to validate DMS(degrees, minutes, and seconds) latitude-longitude format.
**isLength(str [, options])** | check if the string's length falls in a range.<br/><br/>`options` is an object which defaults to `{min:0, max: undefined}`. Note: this function takes into account surrogate pairs.
**isLicensePlate(str [, locale])** | check if string matches the format of a country's license plate.<br/><br/>(locale is one of `['cs-CZ', 'de-DE', 'de-LI', 'fi-FI', 'pt-BR', 'pt-PT', 'sq-AL', 'sv-SE']` or `any`)
**isLicensePlate(str [, locale])** | check if string matches the format of a country's license plate.<br/><br/>(locale is one of `['cs-CZ', 'de-DE', 'de-LI', 'fi-FI', 'pt-BR', 'pt-PT', 'sq-AL', 'sv-SE', 'en-IN', 'hi-IN', 'gu-IN', 'as-IN', 'bn-IN', 'kn-IN', 'ml-IN', 'mr-IN', 'or-IN', 'pa-IN', 'sa-IN', 'ta-IN', 'te-IN', 'kok-IN']` or `any`)
**isLocale(str)** | check if the string is a locale
**isLowercase(str)** | check if the string is lowercase.
**isMACAddress(str [, options])** | check if the string is a MAC address.<br/><br/>`options` is an object which defaults to `{no_separators: false}`. If `no_separators` is true, the validator will allow MAC addresses without separators. Also, it allows the use of hyphens, spaces or dots e.g '01 02 03 04 05 ab', '01-02-03-04-05-ab' or '0102.0304.05ab'. The options also allow a `eui` property to specify if it needs to be validated against EUI-48 or EUI-64. The accepted values of `eui` are: 48, 64.

nit: missed this review, perhaps this wasn't necessary. At some point, we actually contemplated to just use country-code only in the locales for stuff like license plates, that really don't depend on language per se.
