Javascript Solutions
Solution 1 - Javascript
Some JavaScript engines can parse that format directly, which makes the task pretty easy:
function convertDate(inputFormat) {
function pad(s) { return (s < 10) ? '0' + s : s; }
var d = new Date(inputFormat)
return [pad(d.getDate()), pad(d.getMonth()+1), d.getFullYear()].join('/')
}
console.log(convertDate('Mon Nov 19 13:29:40 2012')) // => "19/11/2012"
Solution 2 - Javascript
This will ensure you get a two-digit day and month.
function formattedDate(d = new Date) {
let month = String(d.getMonth() + 1);
let day = String(d.getDate());
const year = String(d.getFullYear());
if (month.length < 2) month = '0' + month;
if (day.length < 2) day = '0' + day;
return `${day}/${month}/${year}`;
}
Or terser:
function formattedDate(d = new Date) {
return [d.getDate(), d.getMonth()+1, d.getFullYear()]
.map(n => n < 10 ? `0${n}` : `${n}`).join('/');
}
