Example 1: Format The Date

// program to format the date
// get current  date
let currentDate = new Date();

// get the day from the date
let day = currentDate.getDate();

// get the month from the date
// + 1 because month starts from 0
let month = currentDate.getMonth() + 1;

// get the year from the date
let year = currentDate.getFullYear();

// if day is less than 10, add 0 to make consistent format
if (day < 10) {
    day = '0' + day;
}

// if month is less than 10, add 0
if (month < 10) {
    month = '0' + month;
}

// display in various formats
let formattedDate1 = month + '/' + day + '/' + year;
console.log(formattedDate1);

let formattedDate2 = month + '-' + day + '-' + year;
console.log(formattedDate2);

let formattedDate3 = day + '-' + month + '-' + year;
console.log(formattedDate3);

let formattedDate4 = day + '/' + month + '/' + year;
console.log(formattedDate4);

Output

08/26/2020
08-26-2020
26-08-2020
26/08/2020

In the above example,

1. The new Date() object gives the current date and time.

let currentDate = new Date();
console.log(currentDate);
// Output
// Wed Aug 26 2020 10:45:25 GMT+0545 (+0545)

2. The getDate() method returns the day from the specified date.

let day = currentDate.getDate();
console.log(day); // 26

3. The getMonth() method returns the month from the specified date.

let month = currentDate.getMonth() + 1;
console.log(month); // 8

4. 1 is added to the getMonth() method because month starts from 0. Hence, January is 0, February is 1, and so on.

5. The getFullYear() returns the year from the specified date.

let year = currentDate.getFullYear();
console.log(year); // 2020

Then you can display the date in different formats.
