Formatting Datetime into ISO Formats

Source

The ISO 8601 format is a standard format for datetime strings. You can easily convert a Date object into a string print out of the datetime in this formation in JavaScript.

Example

const event = new Date('05 October 2011 14:48 UTC');
console.log(event.toString());
// expected output: Wed Oct 05 2011 16:48:00 GMT+0200 (CEST)
// (note: your timezone may vary)

console.log(event.toISOString());
// expected output: 2011-10-05T14:48:00.000Z

Above you can see that you create a new date object and the toISOString() function is a built in class function for the date object.
