How to convert mmddyyyy date format to mm/dd/yyyy in nodejs [duplicate]-CodePudding

I have a dateformat

date="11032020"(mmddyyyy)

output expected:11/03/2020

I want to convert this to mm/dd/yyyy in nodejs.I am a begineer to nodejs. I saw many posts where they convert from mm-dd-yyyy to different format or related.I tried converting to ISO but that did not work out.

I am not able to convert mmddyyyy to different format.

Could you please help me out in this.

CodePudding user response：

If you're certain that the input is MMDDYYYY and don't need to validate it, you could use a regular expression:

let format_date = input => input.replace(/(\d{2})(\d{2})(\d{4})/, "$1/$2/$3")
format_date("11032020") // "11/03/2020"

CodePudding user response：

With moment.js you can do:

const date = "11032020"
const res = moment(date, "MMDDYYYY").format('MM/DD/YYYY')

console.log(res)
