How to format a date as a string in a specific format using JavaScript?

To format a date as a string in a specific format using JavaScript, you can use the toLocaleDateString() method or the Intl.DateTimeFormat object. Here's an example of each method:

Using toLocaleDateString():

const date = new Date(); // Get current date
const formattedDate = date.toLocaleDateString('en-US', {
  year: 'numeric',
  month: '2-digit',
  day: '2-digit',
});

console.log(formattedDate); // Output: MM/DD/YYYY, e.g. 01/31/2022

Using Intl.DateTimeFormat:

const date = new Date(); // Get current date
const formatter = new Intl.DateTimeFormat('en-US', {
  year: 'numeric',
  month: '2-digit',
  day: '2-digit',
});
const formattedDate = formatter.format(date);

console.log(formattedDate); // Output: MM/DD/YYYY, e.g. 01/31/2022

In both methods, we specify the desired format by passing an options object with year, month, and day properties. numeric is used for two-digit numbers and 2-digit is used for zero-padded two-digit numbers. The result will be the date formatted as a string in the specified format.
