Is there any function to get the input that was provided to moment()

In the example below, inputDate bees null.

var date = moment("invalid date");
if(!data.isValid()){
  return { message: "Invalid date", inputDate: date }
}

I can access the input using internals i.e. date._i but was wondering if there's any function that would return the input provided to moment constructor.

You can use creationData()

After a moment object is created, all of the inputs can be accessed with creationData() method:

moment("2013-01-02", "YYYY-MM-DD", true).creationData() === {
    input: "2013-01-02",
    format: "YYYY-MM-DD",
    locale: Locale obj,
    isUTC: false,
    strict: true
}

Here a live example:

var date = moment("invalid date", moment.ISO_8601);
console.log(date.creationData().input);

<script src="https://cdnjs.cloudflare./ajax/libs/moment.js/2.19.4/moment.min.js"></script>

As a side note:

• I've used moment.ISO_8601 in my snippet to prevent Deprecation Warning, as shown here.
• Something quite similar was asked (but not a duplicate) was asked here.
