I was thinking if we could simplify the process of date arithmetic by adding an "add" method, which would add a certain value to the given date object and return the new date. I propose the following structure:

`Date.prototype.add = function(unit:String, value:Number)`

Where `unit` is a specified string to denote hours, minutes, seconds, days, months etc. and `value` is the actual value being added. If `value` is negative, it would end up subtracting that from the specified date.

The reason I am proposing this is that although adding days to a date object is fairly simple, there does not appear to be any straightforward way to add minutes, seconds, and such to a certain date/time. There have been javascript libraries like moment, but it sure would be nice to have this in the ES specs.

Thoughts?

Temporal will provide functionality similar to this

@aclaymore Thank you. Another date-related convenience I would love to have would be to have a destructuring capability for a Date-like object. That is to say, something like -

`const {date, month, year} = new CustomDate(<params>)`

Would it be possible to do it with a `Temporal.PlainDate` object?

Yes you can do:

```javascript
const {day, month, year} = plainDate;

```
