/** * @name isValid * @category Common Helpers * @summary Is the given date valid? * * @description * Returns false if argument is Invalid Date and true otherwise. * Argument is converted to Date using `toDate`. See [toDate]{@link https://date-fns.org/docs/toDate} * Invalid Date is a Date, whose time value is NaN. * * Time value of Date: http://es5.github.io/#x15.9.1.1 * * ### v2.0.0 breaking changes: * * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes). * * - Now `isValid` doesn't throw an exception *   if the first argument is not an instance of Date. *   Instead, argument is converted beforehand using `toDate`. * *   Examples: * *   | `isValid` argument        | Before v2.0.0 | v2.0.0 onward | *   |---------------------------|---------------|---------------| *   | `new Date()`              | `true`        | `true`        | *   | `new Date('2016-01-01')`  | `true`        | `true`        | *   | `new Date('')`            | `false`       | `false`       | *   | `new Date(1488370835081)` | `true`        | `true`        | *   | `new Date(NaN)`           | `false`       | `false`       | *   | `'2016-01-01'`            | `TypeError`   | `false`       | *   | `''`                      | `TypeError`   | `false`       | *   | `1488370835081`           | `TypeError`   | `true`        | *   | `NaN`                     | `TypeError`   | `false`       | * *   We introduce this change to make *date-fns* consistent with ECMAScript behavior *   that try to coerce arguments to the expected type *   (which is also the case with other *date-fns* functions). * * @param {*} date - the date to check * @returns {Boolean} the date is valid * @throws {TypeError} 1 argument required * * @example * // For the valid date: * var result = isValid(new Date(2014, 1, 31)) * //=> true * * @example * // For the value, convertable into a date: * var result = isValid(1393804800000) * //=> true * * @example * // For the invalid date: * var result = isValid(new Date('')) * //=> false */export default function isValid(dirtyDate) {  requiredArgs(1, arguments)
