Changing date format in a Node js project - node.js

Question

I am creating a Node js project which connects to an API and returns a date in the format of 2021-02-28T22:46:01.000-0500 I would like to convert this date to a format of mm/dd/yyyy format. Even better if its mm/dd/yyy hh:mm:ss
This is the current line of code.
this.createdDate = djItem.fields.created
What do I need to add to update the date format?
I am trying to create a function which can be used by two different lines of codes with dates.
this.createdDate = getDate(djItem.fields.created ? djItem.fields.created : 0);
getDate = function(date){
const dateAsNumber = date.parse(createdDate)
console.log(dateAsNumber)
const dateOptions = {
month: "numeric",
day: "numeric",
year: "2-digit",
hour: "numeric",
minute: "numeric",
second:"numeric",
}
const newDateString = new Date(dateAsNumber).toLocaleDateString("us-en", dateOptions);
console.log(newDateString)
}
Current error is createdDate is not defined

Answer 1

You can do this by first parsing the date time format (this will give you a timestamp as a bigint) and then by using the built in data function .toLocaleDateString() function with options that meet your needs.
const dateAsNumber = Date.parse("2021-02-28T22:46:01.000-0500")
// it is now a number
console.log(dateAsNumber)
const dateOptions ={
month: "numeric",
day: "numeric",
year: "2-digit",
hour: "numeric",
minute: "numeric",
second:"numeric",
}
const newDateString = new Date(dateAsNumber).toLocaleDateString("us-en", dateOptions);
console.log(newDateString)
