Returns `true` if a valid date object can be created from the given values, `false` otherwise.
|
|
|
|
- Use the spread operator (`...`) to pass the array of arguments to the `Date` constructor.
|
|
- Use `Date.prototype.valueOf()` and `Number.isNaN()` to check if a valid `Date` object can be created from the given values.
|
|
|
|
```js
|
|
const isDateValid = (...val) => !isNaN(new Date(...val).valueOf());
|
|
```
|
|
|
|
```js
|
|
isDateValid('December 17, 1995 03:24:00'); // true
|
|
isDateValid('1995-12-17T03:24:00'); // true
|
|
isDateValid('1995-12-17 T03:24:00'); // false
|
|
isDateValid('Duck'); // false
|
|
isDateValid(1995, 11, 17); // true
|
|
isDateValid(1995, 11, 17, 'Duck'); // false
|
|
isDateValid({}); // false
|
|
```
