+Checks if a valid date object can be created from the given values.
+
+- 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) => !Number.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
+```
