The delete() method of the CookieStore interface deletes a cookie with the given name or options object. The delete() method expires the cookie by changing the date to one in the past.

This method requires one of the following:

name

A string with the name of a cookie.

Or

options

An object containing:

name

A string with the name of a cookie.

partitioned Optional

A boolean value that defaults to false. Setting it to true specifies that the cookie to delete will be a partitioned cookie. See Cookies Having Independent Partitioned State (CHIPS) for more information.

path Optional

A string containing a path.

url Optional

A string with the URL of a cookie.

A Promise that resolves with undefined when deletion completes.

TypeError

Thrown if deleting the cookie represented by the given name or options fails.

In this example a cookie is deleted by passing the name to the delete() method.

let result = cookieStore.delete("cookie1");
console.log(result);
