@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
