Example Codes: Use of date.toJSON() to Check the Difference in the Time Format of ISO Standard

const date = new Date('2022, 4, 17');
let json = date.toJSON();
const d = new Date('2022, 4, 17, 1:20:05');
let jso = d.toJSON();
console.log(json);
console.log(jso);

Output:

2022-04-17T00:00:00.000Z
2022-04-17T01:20:05.000Z

When we don’t pass the time to the Date object, it considers the time as 00:00:000 and converts the date string to ISO format.
