 **isStrongPassword(str [, options])**   | Check if a password is strong or not. Allows for custom requirements or scoring rules. If `returnScore` is true, then the function returns an integer score for the password rather than a boolean.<br/>Default options: <br/>`{ minLength: 8, minLowercase: 1, minUppercase: 1, minNumbers: 1, minSymbols: 1, returnScore: false, pointsPerUnique: 1, pointsPerRepeat: 0.5, pointsForContainingLower: 10, pointsForContainingUpper: 10, pointsForContainingNumber: 10, pointsForContainingSymbol: 10 }`
 **isTaxID(str, locale)**                | Check if the given value is a valid Tax Identification    Number. Default locale is `en-US`.<br/><br/>More info about exact TIN support can be found in `src/lib/isTaxID.js`<br/><br/>Supported locales: `[ 'bg-BG', 'cs-CZ', 'de-AT', 'de-DE', 'dk-DK', 'el-CY', 'el-GR', 'en-GB', 'en-IE', 'en-US', 'es-ES', 'et-EE', 'fi-FI', 'fr-BE', 'fr-FR', 'fr-LU', 'hr-HR', 'hu-HU', 'it-IT', 'lb-LU', 'lt-LT', 'lv-LV' 'mt-MT', 'nl-BE', 'nl-NL', 'pl-PL', 'pt-BR', 'pt-PT', 'ro-RO', 'sk-SK', 'sl-SI', 'sv-SE' ]`

+**isUUID(str [, version])**             | check if the string is a UUID (version 1, 2, 3, 4 or 5).
 **isVariableWidth(str)**                | check if the string contains a mixture of full and half-width chars.
 **isVAT(str, countryCode)**                | checks that the string is a [valid VAT number](https://en.wikipedia.org/wiki/VAT_identification_number) if validation is available for the given country code matching [ISO 3166-1 alpha-2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2). <br/><br/>Available country codes: `[ 'GB', 'IT','NL' ]`.
