To get the current date and time in ISO 8601 format in JavaScript, you can use the toISOString() method of the Date object. Here's how you can do it: The toISOString() method returns a string representing the date and time in the ISO 8601 format, including the time zone information. The resulting string will look something like this: "2023-08-16T12:34:56.789Z", where T separates the date and time components, and Z indicates the UTC time zone.
