Predict the output of the following javascript code

sessionStorage.setItem('cool_secret', 123);

Forever, the data doesn't get lost.

When the user closes the tab.

When the user closes the entire browser, not only the tab.

When the user shuts off their computer.

The data stored in sessionStorage is removed after closing the tab.

If you used localStorage, the data would've been there forever, unless for example localStorage.clear() is invoked.
