Determining Whether a Date is Tomorrow in JavaScript

When working with dates in JavaScript, it's often necessary to determine whether a given date matches tomorrow. Fortunately, JavaScript provides built-in features that make this task relatively straightforward.

To start, you'll need to create a new `Date` object and then add one day to it using the `setDate()` method. This will give you the date that is one day ahead of the original date. You can then compare the year, month, and day of the two dates to determine whether they match.

Here's an example utility function that demonstrates how to do this:

```

function isTomorrow(date) {

if (!(date instanceof Date)) {

throw new Error('Invalid argument: you must provide a 'date' instance');

}

const tomorrow = new Date(date);

tomorrow.setDate(tomorrow.getDate() + 1);

return date.getFullYear() === tomorrow.getFullYear() &&

date.getMonth() === tomorrow.getMonth() &&

date.getDate() === tomorrow.getDate();

}

```

This function takes a `Date` object as an argument and returns a boolean indicating whether the given date matches tomorrow. If the provided argument is not a valid `Date` object, it throws an error.

In this example, we first check if the provided `date` argument is an instance of `Date`. If it's not, we throw an error. We then create a new `Date` object and set its date to be one day ahead of the original `date` using the `setDate()` method. Finally, we compare the year, month, and day of the two dates to determine whether they match.

By using this utility function, you can easily determine whether a given date matches tomorrow in your JavaScript applications.
