Examples

To be informed when a cookie has changed, you can add a handler to the cookieStore instance using {{domxref("EventTarget.addEventListener", "addEventListener()")}}, like this:

cookieStore.addEventListener("change", (event) => {
  console.log("1 change event");
});

Alternatively, you can use the onchange event handler property to establish a handler for the change event:

cookieStore.onchange = (event) => {
  console.log("1 change event");
};
