 **isStrongPassword(str [, options])**   | check if the string can be considered a strong password 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 }`
 **isTime(str [, options])**             | check if the string is a valid time e.g. [`23:01:59`, new Date().toLocaleTimeString()].<br/><br/> `options` is an object which can contain the keys `hourFormat` or `mode`.<br/><br/>`hourFormat` is a key and defaults to `'hour24'`.<br/><br/>`mode` is a key and defaults to `'default'`. <br/><br/>`hourFormat` can contain the values `'hour12'` or `'hour24'`, `'hour24'` will validate hours in 24 format and `'hour12'` will validate hours in 12 format. <br/><br/>`mode` can contain the values `'default', 'withSeconds', withOptionalSeconds`, `'default'` will validate `HH:MM` format, `'withSeconds'` will validate the `HH:MM:SS` format, `'withOptionalSeconds'` will validate `'HH:MM'` and `'HH:MM:SS'` formats.
 **isTaxID(str, locale)**                | check if the string 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-CA', 'en-GB', 'en-IE', 'en-US', 'es-AR', 'es-ES', 'et-EE', 'fi-FI', 'fr-BE', 'fr-CA', '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', 'uk-UA']`.
+**isTwitterHandle(str)**                | check if the string is a valid Twitter handle (username). Accepts handles with or without the `@` symbol. Handle must be 1-15 characters long and can contain letters, numbers, and underscores only.
 **isURL(str [, options])**              | check if the string is a URL.<br/><br/>`options` is an object which defaults to `{ protocols: ['http','https','ftp'], require_tld: true, require_protocol: false, require_host: true, require_port: false, require_valid_protocol: true, allow_underscores: false, host_whitelist: false, host_blacklist: false, allow_trailing_dot: false, allow_protocol_relative_urls: false, allow_fragments: true, allow_query_components: true, disallow_auth: false, validate_length: true }`.<br/><br/>`protocols` - valid protocols can be modified with this option.<br/>`require_tld` - If set to false isURL will not check if the URL's host includes a top-level domain.<br/>`require_protocol` - if set to true isURL will return false if protocol is not present in the URL.<br/>`require_host` - if set to false isURL will not check if host is present in the URL.<br/>`require_port` - if set to true isURL will check if port is present in the URL.<br/>`require_valid_protocol` - isURL will check if the URL's protocol is present in the protocols option.<br/>`allow_underscores` - if set to true, the validator will allow underscores in the URL.<br/>`host_whitelist` - if set to an array of strings or regexp, and the domain matches none of the strings defined in it, the validation fails.<br/>`host_blacklist` - if set to an array of strings or regexp, and the domain matches any of the strings defined in it, the validation fails.<br/>`allow_trailing_dot` - if set to true, the validator will allow the domain to end with a `.` character.<br/>`allow_protocol_relative_urls` - if set to true protocol relative URLs will be allowed.<br/>`allow_fragments` - if set to false isURL will return false if fragments are present.<br/>`allow_query_components` - if set to false isURL will return false if query components are present.<br/>`disallow_auth` - if set to true, the validator will fail if the URL contains an authentication component, e.g. `http://username:password@example.com`.<br/>`validate_length` - if set to false isURL will skip string length validation. `max_allowed_length` will be ignored if this is set as `false`.<br/>`max_allowed_length` - if set, isURL will not allow URLs longer than the specified value (default is 2084 that IE maximum URL length).<br/>
 **isULID(str)**                         | check if the string is a [ULID](https://github.com/ulid/spec).
 **isUUID(str [, version])**             | check if the string is an RFC9562 UUID.<br/>`version` is one of `'1'`-`'8'`, `'nil'`, `'max'`, `'all'` or `'loose'`. The `'loose'` option checks if the string is a UUID-like string with hexadecimal values, ignoring RFC9565.
