var MyDateString = new Date();

Answer 1

For you people from the future (ECMAScript 2017 and beyond)

Solution

"use strict"

const today = new Date()

const year = today.getFullYear()

const month = `${today.getMonth() + 1}`.padStart(2, "0")

const day = `${today.getDate()}`.padStart(2, "0")

const stringDate = [day, month, year].join("/") // 13/12/2017

Explaination

the String.prototype.padStart(targetLength[, padString]) adds as many as possible padString in the String.prototype target so that the new length of the target is targetLength.

Example

"use strict"

let month = "9"

month = month.padStart(2, "0") // "09"

let byte = "00000100"

byte = byte.padStart(8, "0") // "00000100"
