JavaScript .toISOString()

The .toISOString() method returns a string representation of a date in an ISO 8601-compliant format according to universal time (UTC).

Syntax

date.toISOString();

The string returned from the .toISOString() method will always be 24 or 27 characters long such as YYYY-MM-DDThh:mm:ss.sssZ or ±YYYYYY-MM-DDThh:mm:ss.sssZ, respectively.

Example

In the example below, today’s date is declared and stored in a variable. It is then invoked against the .toISOString() method:

const today = new Date();

console.log(today.toISOString());
