how to format a date from an existing dateformat

Question

How can i format a date in javascript?

let date = '2022-01-01';
let fd = date.toLocaleString("nl-NL"); // in dutch format
alert(fd); // outputs also 2022-01-01; should be 01-01-2022

`"aaaa".toLocaleString("nl-NL")`. Your `date` is not in fact a `Date` — Luca Kiebel, Jan 08 '22 at 18:24
it should be .toLocaleDateString('nl-NL') -> https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString — AchoVasilev, Jan 08 '22 at 18:26

You are not constructing a Date() object.

const date = new Date('2022-01-01')
let fd = date.toLocaleString("nl-NL");
//or make it by yourself
//let fd = date.getDate() + '-' + (date.getMonth() + 1) + '-' + date.getFullYear()
console.log(fd);

let date = '2022-01-01';
var options = {year: "numeric", month: "numeric", day: "numeric"};
fd = (new Intl.DateTimeFormat("en-AU", options).format(new Date(date))).replace(/\//g, '-');
alert(fd);

try this.
