Moment.js Filter out a object whose date property is not after current date

I am using moment.js in my predicate function for the filter method on a array of objects who each have an expiration_date property.

I would like to filter out the object whose expiration_date property is older than today. In my sample array it would be the last one.

let dateOfObjects = [
  {
    expirationDate: "9999-12-31",
  },
  {
    expirationDate: "9999-12-31",
  },
  {
    expirationDate: "9999-12-31",
  },
  {
    expirationDate: "9999-12-31",
  },
  {
    expirationDate: "9999-12-31",
  },
  {
    expirationDate: "1999-12-31",
  },
];

	dateOfObjects.filter((el) => {
	  return moment.utc(el.expirationDate).isAfter(moment()) === true;
	});

I tried to console this before the return

console.log('moment.utc(el.expirationDate).isAfter(moment()) ', moment.utc(el.expirationDate).isAfter(moment()) === true);

And it is logging true for all the last, but when I console.log dateOfObjects I still see it?!

What on earth am I doing wrong?

This example above is in a async function below...

async getAllDateStatuses(): Promise<StdDateStatus[]> {
		let dateStatusEntities: StdDateStatusEntity[] = null;
		dateStatusEntities = await this.dbService.getConnection().getRepository(StdDateStatusEntity).find();

		dateStatusEntities.filter((el) => {
			return moment.utc(el.expirationDate).isAfter(moment()) === true;
		});

		return this.populateMultiple(dateStatusEntities);
	}

Should that matter?

Your dateOfObjects.filter() works just fine for me.

You should know that

> The filter() method does not change the original array.

Source: Definition and Usage

Hence, doing console.log(dateOfObjects) will give you the same value even though you did dateOfObjects.filter() before it.

So, what you need to do to collect the filtered array is to define dateOfObjects.filter() in a variable

Example:

const filteredObject = dateOfObjects.filter((el) => {
  return moment.utc(el.expirationDate).isAfter(moment()) === true;
});

console.log(filteredObject);

filteredObject will be the variable you want.
