**isISIN(str)** | check if the string is an [ISIN][ISIN] (stock/security identifier).
**isISO8601(str)** | check if the string is a valid [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) date; for additional checks for valid dates, e.g. invalidates dates like `2009-02-29`, pass `options` object as a second parameter with `options.strict = true`.

If `strict` is true, date strings with invalid dates like `2009-02-29` will be invalid. If `strictSeparator` is true, date strings with date and time separated by anything other than a T will be invalid.
