JavaScript how to convert time format to MM/DD/YYYY and if month is single number add 0

I have a date:

 console.log(lastDayDate)

Output:

Sun Apr 30 2023 00:00:00 GMT-0500 (Central Daylight Time)

Then I use:

formattedDate = lastDayDate.toLocaleString().split(',')[0];
console.log(formattedDate)

Output is:

 4/30/2023

How can I change it to :

04/30/2023

    you could fix it with
    `let lastDayDate = new Date("Sun Apr 30 2023 00:00:00 GMT-0500 (Central Daylight Time)");

    let day = String(lastDayDate.getDate()).padStart(2, ‘0’);
    let month = String(lastDayDate.getMonth() + 1).padStart(2, ‘0’); // Se suma 1 porque getMonth() devuelve el mes de 0 (enero) a 11 (diciembre)
    let year = lastDayDate.getFullYear();

    let formattedDate = ${month}/${day}/${year};

    console.log(formattedDate); // Debería imprimir: 04/30/2023`

    You can split the 4/30/2023 bit with / and check whether the date/month is less than 10. Created a function for that (also checks the date):

    let formattedDate = "4/30/2023";

function addZero(originalDate){
  date = originalDate.split("/");
  for (let i = 0; i < 2; i++){
    if (+date[i] < 10){ // Shorthand of parseInt
      date[i] = "0" + date[i];
    }
  }
  return date.join("/");
}
console.log(addZero(formattedDate));

    You can use Date#toLocaleDateString with additional options.

    console.log(new Date().toLocaleDateString('en-US', {
  day: '2-digit',
  month: '2-digit',
  year: 'numeric'
}));

    Since you are using JavaScript, there are a lot of awesome 3’rd party libraries out there that can help you play around date object. The most advisable 2 are momentjs and date-fns.

    Creating a moment instance of a js Date() object is quite easy,

    import moment from 'moment';
const timestamp = new Date();
const momentTimestamp = moment(timestamp);

momentTimestamp.format('MM/DD/YYYY')

    moment.js also has a crazy amount of formats available, for all other requirements.
