Javascript Question posted in
A very good W3school tutorial can be found here.

In JavaScript, how do I parse a Date that is always day followed by the month followed by the year?

I’m using Moment.js to parse the Date from a string, however every time I parse it I have to specify the format the string is in, but my string can either be dd-MM-yy or d/m/yyyy or d-MM-yyyy, its always changing, so writing out all the different formats will be challenging, is there a way to parse it if I know the string will always be the day followed by the month followed by the year? Either with JavaScripts date constructor or a third party library like Moment.js

    Can you share your code, I didnt exactly get it but while I was using moment.js
    and I had date of any kind , we can format is by using

    moment(your_date).format('D-MM-YYYY') or  moment(your_date).format('D/MM/YYYY');

    If that clears your doubt then well and good otherwise let me know what have you sent and what exactly is required in code. Thanks

    read this example code

    const dateString = "05-05-2023"; // example date string in "day-month-year" format

const parts = dateString.split(/[-/]/); // split the string into parts using either "-" or "/" as the delimiter

const year = parts[2];
const month = parseInt(parts[1]) - 1; // subtract 1 from the month because it is zero-indexed in the Date() constructor
const day = parts[0];

const date = new Date(year, month, day);

console.log(date); // Fri May 05 2023 00:00:00 GMT+0000 (Coordinated Universal Time)

    Simply match for numbers (i.e. days, month, year), then use the Date() constructor:

    function parseDate(dateString) {
  const [days, month, year] = dateString.match(/d+/g);
  const monthIndex = month - 1;

  return new Date(year, monthIndex, days);
}

console.log(parseDate("2-5-23"));
console.log(parseDate("02-05-2023"));
console.log(parseDate("02/05/2023"));
