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.

const isDateValid = (...val) => !isNaN(new Date(...val).valueOf());
