Checking for Methods that Date Objects Have We can check for methods that date objects have. To do this, we can use the typeof operator. We check that the getMonth method is a function by using the typeof operator to see if it returns 'function' . If it's true , then we know it's likely that date is a Date instance.
You can use the ! isNaN() function to check whether a date is valid. If x is a Date, isNaN(x) is equivalent to Number.
Check if it is null:
if (date == null) {...}
Check if it is not null:
if (date != null) {...}
