Convert Long Date to Short Date in JavaScript#

If you are working with dates in JavaScript, you may need to convert a long date format to a short date format. There are several ways to do this, depending on your requirements. Here are some examples:

Example 1: Using the toLocaleDateString() Method#

The easiest way to convert a date to a short format is to use the built-in toLocaleDateString() method. This method returns the date as a string, using the browser's default locale and formatting options.

const longDate = new Date('2021-10-22T12:45:00');
const shortDate = longDate.toLocaleDateString();
console.log(shortDate); // Output: 10/22/2021

In this example, we create a new Date object with a long date string, and then use toLocaleDateString() to convert it to a short date string. The output is in the format MM/DD/YYYY, which is the default for the United States.

Example 2: Using the Intl.DateTimeFormat API#

If you need more control over the formatting of the short date, you can use the Intl.DateTimeFormat API. This API allows you to specify the locale, date style, time style, and other options.

const longDate = new Date('2021-10-22T12:45:00');
const formatter = new Intl.DateTimeFormat('en-US', {dateStyle: 'short'});
const shortDate = formatter.format(longDate);
console.log(shortDate); // Output: 10/22/21

In this example, we create a new DateTimeFormat object with the options for the United States and a short date style. We then use the format() method to convert the long date to a short date string. The output is in the format MM/DD/YY.

Example 3: Using String Manipulation#

If you don't want to use built-in methods or APIs, you can convert a long date to a short date by manipulating the string directly.

const longDate = 'Friday, October 22, 2021';
const shortDate = longDate.replace(', 20', '/');
console.log(shortDate); // Output: Friday, October 22/21

In this example, we start with a long date string and use the replace() method to replace the comma and the year with a forward slash. This gives us a short date in the format DD/MM/YY. Note that this method is not very flexible and may not work for all date formats.
