I need to obtain the create date of an order with the following format:

20070702 = YYYYMMDD

So far I was able to obtain the order's create date with the following code:

let order  = this.pos.get_order()

let order_date = order.creation_date

let formatted_date = order.creation_date.getFullYear() + order.creation_date.getMonth() + order.creation_date.getDate()

console.log(order_date)

console.log(formatted_date)

this outputs in the browser's console log like the following:

Fri Apr 17 2020 11:47:57 GMT-0400

2040

How do I get the date format I need?
